How Does An Ultrasonic Sensor Work?

1.	How Does An Ultrasonic Sensor Work?
Answer» The sensor has a ceramic transducer that vibrates when electrical energy is applied to it. The vibrations COMPRESS and EXPAND AIR molecules in waves from the sensor face to a target object. A transducer both transmits and receives sound. The ULTRASONIC sensor will measure distance by emitting a sound wave and then "listening" for a set period of time, allowing for the return echo of the sound wave bouncing off the target, before retransmitting.
