Motion Transmitter and Receiver Sensor
Motion transmitter and receiver sensor is divided into two parts (transmitter and receiver); the working principle is: in a very short period of time can be considered as light transmission time is 0, the transmitter first transmit infrared light signals to inform the receiver to transmit ultrasonic signals at the beginning of the moment and transmit ultrasonic waves; Receiver receives the light signals to record the beginning of the moment and timing until the ultrasonic signals are received , finally according to the distance = speed of sound × time to calculate the distance between the generator and the receiver. The receiver receives the light signal and records the starting moment and times it until it receives the ultrasonic signal and then stops timing to calculate the ultrasonic propagation time. The transmitter circuit of the motion transmitter and receiver sensor first provides a narrow voltage pulse to the piezoelectric sensor, under the action of this pulse, the piezoelectric wafer begins to oscillate and emit ultrasonic pulses outward, and at the same time the transmitter uses a light source to inform the receiver to start timing, and when the receiver receives the pulse, the time (T) used by the transmitter from the emission of the pulse until the receiver receives it is also calculated. There is a screw hole (M6 thread) on the side of the sensor, which can be used to fix the sensor to a suitable device.
