The estimated reading time for this post is 83 seconds

About a year ago I bought a typical Chinese burglar on Ebay, it’s composed of a control unit, a PIR ( passive infrared sensor) and two door sensors.

It is completely wireless and works on 433 Mhz frequency.

After a week the unit no longer works !!!

At this point I only had the sensor, what to do ?!

I want to try to use Arduino to read data coming from the sensors and to build a simple burglar.

My idea is :

– interfacing sensors with Arduino;

– add a noise sensor to detect any suspicious noises at home;

– send an e-mail to my email address in case of suspicious activity (like noise or movement)

– turn on a camera to see what is happening in the house

This is my first project with Arduino and I do not know excessively about electronics, but I do know programming.

First I bought an Arduino UNO, then I searched for a receiver / transmitter 433 Mhz …..

For wireless communication I found these models :

MX05V and MXFS03V

As sensor noise :

FC04

Both are available on ebay (very cheap but with waiting time of about a month in Italy ) .

At this point it was time to connect the sensors to Arduino and understand how to read the data .
