125KHz Ultrasonic transducer measure the distance in the air
20cm~3meter.
1. Description
Ultrasonic transducers or ultrasonic sensors are a type of acoustic
sensor divided into three broad categories: transmitters, receivers
and transceivers. Transmitters convert electrical signals into
ultrasound, receivers convert ultrasound into electrical signals,
and transceivers can both transmit and receive ultrasound.
In a similar way to radar, ultrasonic transducers are used in
systems which evaluate targets by interpreting the reflected
signals. For example, by measuring the time between sending a
signal and receiving an echo the distance of an object can be
calculated.
