A friend of mine who own a shoes store, since he had some missing articles, asked me a way to monitor the door of the stock.
He just want a cheap system, connected to a pc, which will be able to send emails alarm when the stock door will be open during the days-off.
I decided to hack a old usb mouse and use the existing reed switch as click emulator.
A piece of python on a linux box will detect the mouse click as a open/close door alarm, and send a email.
Step 1: Prerequisites
You will need :
- a old wired usb mouse
- a linux box using Xorg/X11 (tested on Linux Mint and Ubuntu)
- a reed switch (not on the photo) or a other mecanical switch
- an iron solder
- terminal blocks
- some cables
