HC-SR04 Ultrasonic Distance Sensor

Ultrasonic Distance Sensor is used to measure distance to the nearest obstacle and generally used for Obstacle avoidance robots. The sensor detects obstacles between 2CM to 4M while providing precise and stable non-contact distance measurements with very high accuracy. It can be easily interfaced to any microcontroller like arduino, raspberry pi, etc.
The module sends eight 40Khz square wave pulses and automatically detects whether it receives the returning signal. If there is a signal returning, a high level pulse is sent on the echo pin. The length of this pulse is the time it took the signal from first triggering to the return echo.
