Ultrasonic Sensor Module HC-SR04

Ultrasonic Ranging Module HC-SR04 provides 2cm - 400cm non-contact measurement function, the ranging accuracy can reach to 3mm. The modules includes ultrasonic transmitters, receiver and control circuit

The HC-SR04 ultrasonic sensor uses sonar to determine distance to an object - just like bats or dolphins do.

This module offers excellent range accuracy and stable readings in an easy-to-use package. It operation is not affected by sunlight or black material (although acoustically soft materials like cloth can be difficult to detect). Similar in performance to the SRF005 but with the low-price of a Sharp infrared sensor.

This sensor is perfect for collision avoidance on your next robotics or multirotor project!

How Ultrasonic Sensor Work:

  • A 40kHz chirp is emitted from the transmitter
  • It bounces off of an object.
  • The echo returns to the microphone.
  • The time it takes to travel to the object and back is used to figure out the distance.
