Schematic of IR Beam Breaker Circuit. TSOP1738 IR sensor module responds to only 38 kHz pulsed infrared rays. It will not sense continuous IR ray from the IR LED. So a transmitter circuit(as one in TV ...

This project is a simple IR Sensor Module Circuit Design that detects nearby objects using infrared reflection. The circuit is ideal for beginners in electronics or embedded systems and can be used in ...

Blind Stick Circuit and Working Fig. 2 shows the circuit diagram of the stick for the blind. It is built around an IR sensor module connected across CON2, a PNP transistor BC558 (T1), a buzzer (PZ1), ...
