Feature: 1. With functions of adjustable delay and light sensitivity, and the light sensor has no flicker. With relay and delay function, when the light is darker than the brightness adjusted by the potentiometer, the relay switch is automatically turned on. It can be used for various light detection alarms, light control delay switches, brightness detection switches, and various street lights can be controlled. Automatically turn on at night, turn off automatically during the day and auto headlights, stage lights, LED lights, traffic light detection switch. 2. Adopts imported chip control, stable and reliable quality. Can achieve automatic light detection, brightness detection, and the detection brightness valve point can be adjusted through the potentiometer. 3. The power supply part has diode protection, filter capacitor and anti‑interference capacitor and 7805 voltage regulator chip, which can provide a stable voltage and prevent the module from burning out when the power supply is reversed. 4. Equipped with a precision adjustable potentiometer to better adjust the sensitivity and delay time; there are power instructions and relay pull‑in instructions. 5. The module is equipped with a high‑power relay, which can control a 10A current load; also comes with a 50cm/19.7in long photoresistor sensor. 6. The module has a delay, and the delay time can be adjusted to solve the flicker problem of the relay when the light is tipping point. 7. The new light‑controlled delay module is equipped with a multi‑turn precision adjustable potentiometer. The sensitivity and delay can be accurately adjusted to the appropriate range, and the application is stable.
