working principle
The kit simulates the reversing radar function. When the kit is far from the obstacle, the lights are not on. When the obstacle is getting closer and closer, the green, yellow, and red LEDs will be lit in turn to remind the driver to pay attention to reversing safety. The circuit is composed of multiple resonance circuits, infrared emission and infrared 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.
