In this tutorial, I am going to show you how to detect the fullness of a paper shredder and send a notification via Gmail using Arduino Uno.
I made this tutorial for beginners! It is really easy!
Let's get started!
Ultrasonic Sensor - HC-SR04 is used to detect the fullness of paper shredder. When the distance between sensor and paper trash is at a threshold, paper shredder is considered to be full.
In this project, when an event occurs, a notification is sent via Gmail.
