Instead, it relies on an ultrasonic distance sensor to detect a hand (or foot) waved in front of the door. An Arduino Leonardo runs the show, sounding a buzzer when the ultrasonic sensor is triggered.

Comparison of Capacitive with Induction Sensors. Capacitive sensing involves charging up plates, so it is somewhat slower than inductive: 10 to 50 Hz, with a sensing distance from 3 to 60 mm.

This IoT-based smart bin project integrates an Arduino Uno R4 WiFi with ultrasonic sensors and a servo motor to automate waste disposal. The system uses proximity detection to open the lid and ...
