Description:
 
The infrared reversing radar is composed of a multi-resonant circuit, an infrared signal transmitting and receiving circuit, an infrared signal amplifying and a voltage comparison circuit, and has the characteristics of simple circuit, low cost and stable circuit operation, and is widely used in various ranging occasions.
Power supply: 6V
Size: 65*45mm

 
Installation and commissioning and simple principle description:
 
1. The infrared transmitting tube HF and the infrared receiving tube HJ have polarity (long legs are positive), please do not install the wrong ones, the mounting direction can be upwards or sideways. RP1 adjusts the reflection distance, RP2 adjusts the sensitivity, LED3 can be bright when the distance is 30cm, LED2 and LED3 are bright when the distance is 20cm, and fully bright when the distance is 10cm. The infrared sensor is covered with white paper to block the reflection effect.
 
2. The time base circuit NE555 and surrounding components form a multivibrator to generate an infrared wave signal, which is output through the third pin of IC2 and drives the infrared transmitting tube HF to emit an infrared signal.
