1. Product description
The infrared reversing radar is composed of multiple resonance circuits, infrared signal transmitting and receiving circuits, infrared signal amplification and voltage comparison circuits. It has the characteristics of simple circuit, low cost, and stable circuit operation. It is widely used in various ranging applications.
2. Installation and debugging and simple principle description
1. The infrared transmitting tube HF and the infrared receiving tube HJ have polarity (the long leg is positive), please do not install it wrongly, the installation direction can be upwards or sideways. RP1 adjusts the reflection distance and RP2 adjusts the sensitivity. You can try to turn on LED3 at a distance of 30cm, LED2 and LED3 at a distance of 20cm, and all on at a distance of 10cm. It is better to use white paper to block the reflection above the infrared sensor. This product is a teaching kit, not an industrial device. It is used for learning, teaching, and hobbies. Please know.
2. The time base circuit NE555 and surrounding components form a multivibrator to generate an infrared wave signal, which is output through IC2's third pin and drives the infrared transmitter tube HF to emit an infrared signal.
