Components of the ultrasonic sensor
Nov 14, 2017

Transmitter: Vibrations generated by the oscillator (usually ceramic, diameter of about 15 mm) to produce ultrasound and airborne radiation.

Receiver: When the vibrator receives the ultrasonic wave, the corresponding mechanical vibration occurs according to the ultrasonic wave and converts it into electric energy, which is used as the output of the receiver.

Control part: By using the integrated circuit to control the transmitter ultrasonic transmission, and to determine whether the receiver receives the signal (ultrasonic), and received signal size.

Power section: Ultrasonic sensors are usually used DC12V ± 10% or 24V ± 10% external DC power supply, the internal voltage regulator circuit sensor.
