Creating an alarm on the Arduino motion sensor. Home alarm or using motion sensor and LCD monitor with Arduino. Key Features SIM900 SHIELD
Are special hardware platforms, on the basis of which you can create various electronic devices, including. The devices of this type are characterized by a simple design and the ability to program the algorithms of their work. Due to this, created with Arduino GSM. signaling , It can be maximally adjusted for an object that it will guard.
What is the Arduino module?
Arduino is implemented in the form of small boards that have their own microprocessor and memory. The board also contains a set of functional contacts to which various electrified devices can be connected, including the sensors used for security systems.
The Arduino processor allows you to upload a program written by the user on your own. Creating its own unique algorithm, you can provide optimal modes of operation of security alarms for different objects and for various conditions use and solved tasks.
Is it difficult to work with Arduino?
Arduino modules are highly popular among many users. This became possible due to its simplicity and accessibility.
Programs for managing modules are written using conventional C ++ and add-ons in the form of simple input / output process management functions on the module contacts. In addition, the programming can also use the ARDUINO IDE free software environment operating under Windows, Linux or Mac OS.
The Arduino modules are significantly simplified the procedure for assembling devices. GSM alarm Arduino can be created without a need for a soldering iron - the assembly occurs using a bold board, jumpers and wires.
How to create alarm with arduino?
To the basic requirements that the GSM created the alarm on Arduino must include:
- notify the owner of the object of hacking or penetration;
- support external systems such as sound siren, signal lights;
- control signaling via SMS or call;
- offline work without external food.
To create alarm, you will need:
- arduino module;
- a set of functional sensors;
- or modem;
- offline power supply;
- external executive devices.
A distinctive feature of Arduino modules is the use of special extension boards. With their help connecting all additional devices To Arduino, which are required to build configuration security system. Such cards are installed on top of the Arduino module in the form of "sandwich", and the corresponding auxiliary devices are connected to the board themselves.
How it works?
When one of the connected sensors is triggered, the signal is transmitted to the Arduino module processor. Using the downloaded user software, the microprocessor produces its processing on a specific algorithm. As a result, a command can be formed on the operation of an external actuator, which is transmitted to it through the appropriate pairing fee.
To ensure the possibility of mandrel of warning signals to the home or apartment owner, which is guarded, to the Arduino module, through the extension fee, a special GSM module is connected. It establishes a SIM card of one of the cellular providers.
In the absence of a special GSM adapter, its role can also be performed mobile phone. In addition to sending SMS messages with alarm warning and dialing, the presence of a cellular will allow you to control GSM signaling to arduously remotely, as well as monitor the state of the object by sending special requests.
"Note!
To communicate with the owner of the object, in addition to GSM modules, conventional modems that provide communication via the Internet can be used. "
In this case, when the sensor processed by the signal processed by the processor is transmitted via a modem to a special portal or site. And already from the site automatically generates warning SMS or mailing to a tied e-mail.
conclusions
Using Arduino modules will allow users to independently design GSM alarms that can work with different function sensors and manage external devices. Due to the possibility of using various sensors, the alarm function can significantly expand and create a complex that will monitor not only the safety of the object, but for its condition. For example, it will be possible to control the temperature on the object, fix the leakage of water and gas, overlapping them in the event of an accident and much more.
This project concerns the development and improvement of the system to prevent / control any attempts to penetrate the thieves. Designed security device Uses the built-in system (turns on the hardware microcontroller using open software code and GSM modem) based on GSM technology (global mobile system).
A security device can be installed in the house. Interface sensor security alarm Also connected to the security system based on the controller.
When trying to penetrate the system transmits a warning message (for example, SMS) to the owner on a mobile phone or any pre-configured mobile phone for further processing.
The security system consists of microcontroller Arduino. Uno and standard SIM900A modem based on GSM / GPRS. The entire system can feed from any power supply / 12V 2A battery.
The following is shown in the ARDUINO security system.
The operation of the system is very simple and does not require clarification. When the system is supplied, it goes into the standby mode. When the J2 Connector conclusions are shortened, the pre-programmed warning message is transmitted to the required mobile number. You can connect any penetration detection detector (such as a light protective device or motion sensor) to the J2 input confctor. Note that the active-low (L) signal at the output 1 of the Connector J2 activates the triggering of the security alarm.
Moreover, optional "Call - Alarm" is added to the system. It activates the phone call when the user clicks the S2 button (or when another electronic unit initiates alarm). After pressing the "Call" button (S2), the call can be canceled by pressing another S3 button - the "END" button. This option can be used to feed alarm in the case of "missed call" in case of penetration.
The scheme is very flexible, so it can use any SIM900A modem (and, of course, Arduino Uno fee). Carefully read the documentation on the modem before the start of the assembly. This will make it easier and make a pleasant process manufacturing process.

Now you need to select the GSM module, because our alarm must be able to notify the owner of the car. So, you need to "google" ... Here is an excellent sensor - SIM800L, the size is simply wonderful.
I thought and ordered it from China. However, everything turned out to be not so rosy. The sensor simply refused to register the SIM card on the network. It was tested all that only possible - the result is zero.
Found kind peoplethat provided me with a sharp piece - SIM900 Shield. This is the already serious thing. In Shield and a microphone connector and headphone, a full-fledged phone.

OK, but you need to take readings from some sensors to notify the owner. Suddenly the car is evacuated, then the position of the car will clearly change in space. Take an accelerometer and gyroscope. Excellent. Tax, now we are looking for a sensor.
I think that the GY-521 MPU6050 is exactly suitable. It turned out that there is a temperature sensor in it. It would be necessary to use it, there will be such a "Killer Fich". Suppose that the owner of the car put it under home and left. The temperature in the car will be changed "smoothly". What will happen if the attacker tries to penetrate the car? For example, it will work out the door. The temperature in the car will begin to change rapidly, as the air in the cabin will begin to mix with the air ambient. I think that will work.

About connecting each sensor in Google a huge number of articles. And invent new bikes I have no desire, so I will leave links to simple and working options.Today we will talk about how with Arduino Collect security system. Our "guard" will watch out one contour and manage one infidel.
For Arduino, this is not a problem, and, as you will see on the program code and by the device diagram, you can easily increase the number of protected access points and the number of alert or indication devices.
Security system You can apply to protect both large objects (buildings and structures) and small objects (boxes, safes), and even portable cases and suitcases. Although you need to be careful if you install the security system, for example, on a suitcase with which you decide to go on a journey, and the alert system will work in some airport, then I think you have a serious conversation with your local security service :-)
Simplified the principle of operation of the device is as follows (Fig. 1). After powering on the power, the device switches to the operating mode and waits for protection. Staging and disarming is carried out by one button. To enhance the security, this button is better to arrange inside the protected area (safe or casket). Before turning on the security mode, the door must be opened. When you turn on the security mode (pressing the button) electronic circuit Waiting until you close the door to the room (safe door, casket cover, etc.).
On the door (or door) there must be a terminal switch of any type, about it later. Climbing (or blurring), the limit switch will inform the device that the protected circuit is closed, and the device will go into the protection mode. On the transition to the protection mode, the system will notify two short signals (as in car alarms). In this mode, the device "catches" the opening of the door. After opening the door, the system is waiting for a few seconds (this is the value is customizable, for the premises of about ten seconds, for the box of one or two) shutdown of the protection mode, if this does not occur, the siren turns on. The algorithm and scheme are designed so that it is possible to disable the siren, only completely dismissed the case and turning off the power.
Device security system Very simple (Fig. 2). At the heart of the fee Arduino. The limit switches are connected as the usual button through pull-up resistors. On the contractions will stop separately. They are normally closed and normally open. You can enable the usual button as a terminal, only conventional button Very large, the play of the door is usually more. Therefore, it is necessary to come up with some pusher for the button and spring so as not to break the door button. Well, if not too lazy, you can walk to the store and buy a magnetic switch (GERCON) (Fig. 3), it is not afraid of dust and contamination.
A limit switch for auto alarms is suitable (Fig. 4). It should be noted, the program is written in German. With the door closed, its contact is closed. If you use a switch from car alarm, then with the door closed it will most likely open, and in the appropriate locations the code will need to be changed 0 on 1 and vice versa.
As a siren, we propose to use the sounding of sound PKI-1 Ivolga of Belarusian production (Fig. 5). Power supply 9 - 15 V, operating current 20 - 30 mA. This allows you to use it with battery powered. At the same time, he "issues" 95 - 105 dB.
With such characteristics from the Crohn battery, it will sound several dozen minutes. I found it on the Internet for 110 rubles. There is a geron with a magnet worth about 30 rubles. The switch from car alarm in auto parts was purchased for 28 rubles. The CT315 transistor can be taken with any letter or replace any modern low-power silicon transistor with appropriate conductivity. If the volume of one batch is not enough (who knows, maybe you want to be heard for many kilometers), you can connect several alarms in parallel or take more powerful, only in this case and the transistor must be replaced with a more powerful one (for example, a familiar transistor Assembly ULN2003). As connectors for connecting Hercon and Siren, I used the simplest connectors for audio / video devices - the price of Radiore 5 rubles. For a couple.
The device body can be glued from plastic or plywood; If a serious object is protected, it is better to make it metallic. Batteries or nutrition batteries to increase reliability and safety should be placed inside the case.
To simplify the program code, elements of energy saving were not used, and the batteries are not enough for a long time. You can optimize the code, and even better to convert radically by applying the processing of events to interrupts and sleep MC mode. In this case, nutrition from two square batteries included in series (9 V) must be enough for several months.

Good day! Again, a multi-review of Chinese electronic components, as usual of everything we gradually, I will try to shorter, but will it work? So, meet, GSM alarm cost up to 700 ₽. Interesting? I ask for "Cut"!
Baister! Before starting, I recommend to look into this, less components and large autonomy. So, "technical education", basic alarm requirements:
1) Notify when the sensors are triggered.
2) In the event of a power off, some autonomy should be provided.
3) Alarm management via SMS and calls.
Due to the fact that the alarm creation process was delayed for several months and some sellers no longer sell those components that were purchased from them, links will be updated on goods of other sellers who have the maximum or close to the maximum number of sales of goods and best price. Prices in the review are relevant at the date of his writing.

Memory optimization. Busy: 68% SRAM, 99% Flash Memory.
GSM_2017_08_10-12-17.HEX - SMSON / SMSOFF, ReeDSWITCHON / REEDSWITCHOFF, Piron / Piroff commands are removed and all connected with them. The DelayBeForeAlarm team is replaced by advanced commands. Changed the output of the info command. Optimized ListConfig command output into the console. Now any digital sensors with a high or low level of response can be connected to Pins D6 and A0, including Herkes. Pins D6 and A0 must be attracted to the ground (GND) through resistance 10 (20) com. If the sensor is configured to a low response level (enabled in Herrock mode), the integrity of the chain is checked. The logical response level of the inputs D6 and A0 (+ 5V or GND) can be changed, after changing the logical level, the device will automatically be rebooted. For each of the sensors (MAIN, SECOND, PCF extension cards), when triggered, it can be installed on which a notification will be notified (SMS and / or voice call). "PIR SENSOR" is renamed to SECOND SENSOR. Fixed the operation of the extension board, the error due to which the device has always notified about the triggering of the sensors, regardless of whether the device is supplied or not. Now you can select the mode of operation in which the device can monitor the extension board sensors in both the guardon mode and when the GuardOff) is turned off. Added PCFForceon / PCFforceoff commands, MainsensorlevelHigh / Mainsensorlevellow / Mainsensorleveloff, SecondsensorlevelHigh / Secondsensorlevellow / Secondsensorleveloff, MaindelayBeforealarm, SeconddelayBeforealarm, PCFDELAYBEFOREALARM. Busy: 68% SRAM, 99% Flash Memory.

UPD. When using motion sensor, To eliminate false positives when working modem, you need between Pina GND. and A0. Arduino. put resistance, thanks talk to a friend
AllowPhone \u003d ("70001234501", "70001234503", "70001234504", "70001234505") - numbers which are allowed to control the protection.
ALARMPHONE \u003d ("70001234501", "70001234502") - numbers for sending SMS notifications when the sensor is triggered and notified for the removal or arming. The first number in the list will be called when the sensor is triggered if the Ringon command is executed, the default option is enabled. This is done because SMS messages can come with some delay, and the call must go right away.
If you have received a call from a permitted number or an SMS message with the Guardon / Guardoff command, then, depending on the current security status, an SMS message on the stage or removal from security to the numbers listed in the Alarmphone array will also be sent to the SMS message to the number from which he received a call.
When triggered the sensor SMS messages are sent to all numbers from the massif (list) of alarmphone and will be called voice call to the first number from this array.
Light indication:
The LED glows in red - put on guard.
LED glows green color - Disabled with security, turns on / off the SMS command LEDON / LEDOFF.
The LED constantly flashes in blue - signals that C arduino is all right, the fee does not depend, is used exclusively for debugging, it turns on / TestOff SMS command.
* The code is present in the code LEDTest (), it flashes the blue LED, is made only to monitor Arduino, flashes - it means it does not blink - it hung. It has not yet hung :)

Connecting 2 or more sensors for open firmware (only for this firmware Sketch_02_12_2016.ino)
To connect additional generic sensors, use free digital pins d2, d3, d5 or d7. Connection diagram with an additional sensor on D7. 
Necessary changes in the firmware

And one more thing:
1. The diodes are better to use 2 A current, as the module infects the current at 1 A and we still need to feed the Arduino and the modem. This instance uses 1N4007 diodes, if we fail to replace 2 A.
2. All resistors for the LED used on 20 com, in order not to light the entire corridor at night.
3. On the armless sensor between the GND pin and pin D6 also hung the resistor on 20 com.
That's all. Thanks for attention! :)
