Introduction: DIY Motion Detection SMS Alarm System

About: Awesome Electronics Tutorials, Projects and How To´s

In this project I will combine a cheap PIR motion sensor with a TC35 GSM module to build an alarm system which sends you an "INTRUDER ALERT" SMS whenever somebody tries to steal your stuff. Let's get started!

Step 1: Watch the Video !

This video gives you all basic information you need to get this build right. But I will give you some additional advice in the next steps.

Step 2: Order Your Parts !

Step 3: Build the System !

Here you can find the schematic which you should always follow during your hardware build ! If you do so then everything will work out.

Step 4: Upload the Code !

Here you can download the sketch for the arduino mini. Make sure to download the timer library before trying to upload the code.

Timer library: https://github.com/JChristensen/Timer

Step 5: Success !

You did it ! Now you can enjoy more safety with your new alarm system.

    Hello. It's probably late, but can somebody help me? I think that there is problem with the code. Look at my video with the problem.
    // The video is for GS!, but he don't have a time

    Thank you for help guys ! ♥♥

    Is it possible if I add a jpeg camera and capture an image and save it to sd card module or instead of message alert a jpeg picture will be send?

    Hi,

    Maybe a bit late, but I was wondering if it is also possible for the system to work without the SMS part. So in other words just have an alarm without the GSM module?

    1 reply

    Of course it would. If you want the "smarts" i.e. the delay, you can keep the arduino, but you can make it work just with a transistor and a relay on the output of the PIR module

    nice can you pls one help to me

    Fow such purposes I use cheap mobile phone with fast dial function. For example, lasting press (above one sec) to button 1 will cause voice mail call. You only need to solder two wires to button contacts and set up your number such as voice mail

    hello, I javasichiro of Indonesia
    I want to consult, for FTDI component, Pro Mini whether it can be replaced with the Arduino Uno / Arduino Nano (though brief) and GMS TC35 module for me to replace it with a GSM module Mini Sim900a V4.0?

    And should be able to disarm it too, remotely with mobile phone perhaps

    Nice build! U could use reed switch at door too.

    Dat spider at 6:27 :p

    How do you activate the GSM with the cell carrier? We use M2M modems (verizon) at work but no one knows how to activate them, they want to use a hotspot plan at 60.00 a month.

    just an idea: instead of spending the money on a gsm module you could use a RPI/Ethernet shield and instead of sending a SMS, send a email. then using ifttt you could automatically send the text.

    What about the case, where can I get that?

    Go to a hardware store and ask for an ip66 junction box with rubber grommets

    Thanks.

    Maybe a stupid question, but what are the two potentiometers for in the top of the box for? (they don't appear in the schematic) And why use a waterproof enclosure with non-waterproof switches and pots - cost?

    1 reply

    The potentiometers control the delay time and distance of the PIR sensor.
