5V 12V 24V Light Sensing Photoresistor Relay Module For Timed Light Control

When this module senses the light or the light is dark, the relay is closed! ! !

Automatic light detection, brightness detection, the detection brightness valve point can be adjusted through the potentiometer, and with its own relay and delay function. When the light is brighter than the brightness adjusted by the potentiometer, the relay switch is automatically turned on and has a delay time. Function, can do various light detection alarms, light control delay switch, brightness detection switch, can control related equipment through light control, the product has the functions of adjustable delay and light sensitivity, and the light sensor does not flicker. (Compared with photoresistor, it has better directivity, it can perceive the light source in a fixed direction, and detect the light directly in front of the photodiode. It is difficult to detect the surrounding area. It is often used for the light-seeking function)

8. Module size: 63.5x38.5x18.5mm

6. Delay range: plug in S2. Delay 1-20 seconds adjustable, without S2, 1-200 seconds adjustable.

When the light is at the set critical point, the light does not suddenly turn to a bright state, but slowly changes from dark to bright. If there is no delay, the relay will have a flickering problem. After the delay is added, this problem can be avoided The occurrence of this makes the relay work stable and reliable.
