Ultrasonic Sensor

This HC-SR04-Ultrasonic Range Finder is a very popular sensor that is found in many applications where it requires measuring distance and detecting objects.

The module has two eyes like projects in the front which forms the Ultrasonic transmitter and Receiver.  The HC-SR04 ultrasonic sensor uses sonar to determine the distance to an object like bats or dolphins do.

Ultrasonic Ranging Module HC-SR04 provides 2cm-400cm non-contact distance sensing capabilities, Ranging accuracy up to 3mm.

This Ultrasonic Sensor can be attached to your project using a mounting bracket.
