Among them, the transmitting part consists of a transmitter and a transducer, and the transducer can convert the energy generated when the piezoelectric wafer is vibrated by the voltage excitation into ultrasonic waves, and the transmitter will transmit the generated ultrasonic waves; the receiving part consists of a transducer and an amplifier circuit.
Receiving part consists of transducer and amplifier circuit, the transducer receives the reflected ultrasonic waves, due to receive ultrasonic waves will produce mechanical vibration, the transducer can be converted to mechanical energy into electrical energy, and then by the amplifier circuit to amplify the electrical signal generated;
The control part is the control of the whole working system, first control the transmitter part of the transmitter ultrasound, and then the receiver part of the control, to determine whether the received ultrasound is emitted by their own ultrasound, and finally identify the size of the received ultrasound;
The power supply part is the power supply device of the whole system. In this way, under the action of the power supply and under the control of the control part, the transmitter and the receiver work together to fulfil the required functions of the sensor.
