In this project, I am going to show you how to detect someone stealing your valuable stuff. If detected, Arduino sends a notification via Gmail and makes an alert sound and light.
Detecting Something is Taken Away
To detect treasure present or not, I put the treasure on the force sensor. This sensor let us know how heavy treasure is. If output value of sensor is below a threshold, Its means the treasure is not present and someone took it away.
Force sensor (electronic part is hidden below table)
Laptop overlays force sensor.
Electronic part should be hidden under table.
If event is detected, Arduino will make an alert sound and light, and send an Gmail notification to owner.
Similar Project but Different Platform
This project does the same works but it used other hardware platform.
