Street lamp following controller

The utility model discloses a street lamp following controller, and the controller comprises an infrared sensing module, a light-sensitive element, a microcontroller, an isolation drive circuit, and an LED lamp power supply circuit. The infrared sensing module is connected with the microcontroller, detects an infrared signal of a vehicle or a pedestrian on a road, and then converts the infrared signal into a pulse signal which is sampled by the microcontroller. The light-sensitive element is connected with the microcontroller. The light-sensitive element converts environmental brightness into a pulse signal which is sampled by the microcontroller. The microcontroller, the isolation drive circuit and the LED lamp power supply circuit are sequentially connected with each other. The controller provided by the utility model receives the signals of the infrared sensing module and the light-sensitive element through the microcontroller. In a certain period of time, the controller judges whether the pedestrian or th
