Ultrasonic sensor is an electronic sensor that measures distance by emitting ultrasonic pulses and listening for echoes. Different algorithms are then applied to turn these echo-lengths in to a distance measurement. Ultrasonic sensors are extremely versatile, cost effective and easy to use in a variety of applications.

Ultrasonic sensors are used in automatic car washes, gas stations, sewers, warehouses and many other places to measure the distance or the dimensions of objects. They use ultrasonic waves that allow you to measure distance without touching contact between the sensor and the object. Ultrasonic sensors have a very long life when a passive reflector is used with them. They are reasonably easy to calibrate and their operating temperature range is wide enough (from -10 °C to +60 °C). Ultrasonic sensor is a sensor that uses ultrasonic waves to detect an object, which has good performance and a sensing angle from 0 to 360 degrees.
