Introduction: DIY Motion Detection SMS Alarm System

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 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.

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?

author
billgeo (author)LarsM32016-05-07

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

good job mr

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?

author
Impetus37 (author)2015-05-01

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

author
Impetus37 (author)2015-05-01

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.

jimmerforpoy (author)2015-04-30

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.

NICE

RobP1 (author)2015-04-26

What about the case, where can I get that?

author
Eep42 (author)RobP12015-04-27

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

author
RobP1 (author)Eep422015-04-27

Thanks.

author
GreatScottLab (author)Eep422015-04-27

Good plan :-)

duncan_a (author)2015-04-26

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?

author
GreatScottLab (author)duncan_a2015-04-27

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

Hi, Nicely done project. One question: I'm in the US, can you please tell me the manufacturer and model of the "project box" you have used? It looks like a nice box to use for other projects.Thanks!

author
GreatScottLab (author)Bob15602015-04-27

I don't know the manufacturer. Just visit your next hardware store. They will surely have something like this.

According to comments on Amazon the GSM module in this project is not compatible with American cell phone networks. Does anyone know about this?

author
pnosko (author)2015-04-26

I really like this build. Could you go into more detail about how the GSM module connects to the mobile network? How does it do this? Is there no configuration required?

author
GreatScottLab (author)pnosko2015-04-26

This might help: https://youtu.be/gVGD-f8SQSI

pnosko (author)GreatScottLab2015-04-26

Yes, thank you. And the voice is familiar! ;)

Snikbuen (author)2015-04-26

Is it possible to expand the system and make use of several inputs? Then you can have SMS telling you in what room you have an intruder, or if you have a waterleak, If you operate it on batt.power you can also get an SMS if you have powerloss in you house. I`m getting all kinds of ideas here. I have to stop... :-) Very nice project!!

This is very nice. I love it.
