How to make a Raspberry Pi surveillance and alarm

It’s the 1st of July,  and hopefully you are lucky enough to go on holiday soon, this is a great way to make a useful project right before leaving home alone!

This is a cheap but powerful system of surveillance and alarm,  we know it’s always hard to leave home  for a long trip, but now you can be confident!

We’d love to thank first @sistemasorp , the #biicontest finalist that hacked this project!

How to make a Raspberry Pi surveillance and alarm

Pre- Requisites:

The Diagram:

The UBEC and PIR module can be powered from 7 to 12 volts. The out VCC wire of UBEC goes to GPIO pin 2 (5V), the GND one goes to GPIO pin 6 (GND).

The PIR module signal is open drain, so it needs a pullup resistor. A wire from GPIO 1 (3V3) to a 10K resistor lead, from the other resitor lead there are two wires: the first to GPIO pin 12 (GPIO1) and the second to PIR alarm.
