Sonar Range Finder -High Performance Ultrasonic Sensor Module

An ultrasonic sensor detects and measures the distance of a target object using ultrasonic sound waves and converts the reflected sound into an electrical signal. This sonar range finder module is used for measuring distance, object sensors, motion sensors, etc. It emits an ultrasonic wave at 40 kHz which will go and bounce back after hitting an object. By knowing the time travelled and the speed of the sound, we can calculate the distance (speed=distance/time). Ultrasonic waves are much faster than regular sound and as humans, we won’t be able to hear them.

The two main components of this sensor are the transmitter and receiver. Hence the transmitter produces the sound and the receiver, receives it. This technology is used for measuring wind speed and direction and speed through air or water. Thus it generates sound waves in the ultrasonic range, above 18,000 Hz by turning electrical energy into sound, then upon receiving the echo turn the sound waves into electrical energy which can be measured and displayed. This compact sonar range finder comes in a size less than 1 cubic inch with easy mounting. Moreover, it features real-time automatic calibration and noise rejection. Thus resulting in virtually noise-free distance readings even in environments with changing acoustic and electrical noise.
