Description

The HC-SR04 is an Ultrasonic distance sensor. From one side, it emits ultrasound pulses up to every 10 microseconds that bounce off objects, and the other side listens for the pulses. By comparing the time between a pulse emission and a pulse reception (a trigger and an echo), a computer program can detect objects in front of the sensor. The sensor works with 3.3V and 5V DC voltages, with some caveats. It can detect objects 2-450cm away when it’s given 5V power.

Project Rover uses an HC-SR04 mounted at the front of the car chassis to detect objects!
