T/R-40 series of ultrasonic sensors works by piezoelectric effect. Usually we also call it transducer. This type of transducer is suitable for anti-theft alarm and remote.
The shape, size and circuit symbols of T/R-40-XX series of ultrasonic sensors.
The ultrasonic transmitter circuit composed of discrete structure.
T/R-40-16 will emit a string of 40kHz ultrasonic signals. The circuit voltage is 9V, operating current is 25mA, control distance can up to 8m.
Ultrasonic transmitter circuit composed of 555.
The 40kHz oscillation pulse drives T-40-16 output from 555 of the pin 3, that makes it emit 40kHz ultrasonic signal. Circuit voltageis 9V, operating currentis 40 ~ 45mA, the control distance is more than 8m.
