Prime Intact Ultrasonic Sensor Module HC-SR04 FOR Distance Measuring Electronic Components Electronic Hobby Kit

Ultrasonic ranging module hc - sr04 provides 2cm - 450cm non-contact measurement function,the ranging accuracy can reach to 3mm. The HC-SR04 is an ultrasonic module that is best used for development boards compatible with arduino, ARM and other microcontrollers.This HC-SR04-Ultrasonic Distance Measuring Sensor is a very popular sensor which is found in many applications where it requires to measure distance and detect the objects.These ultrasonic module is designed to provide High sensitivity to detect sounds of objects and measure the distance.The HC-SR04 ultrasonic sensor uses sonar to determine the distance to an object like bats or dolphins do.This Ultrasonic Sensor module is a transmitter, a receiver, and a control circuit in one single pack.It offers excellent range accuracy and stable readings in an easy-to-use package.Ultrasonic sensors generate high frequency sound waves and evaluate the echo which is received back by the sensor
