Module function description:

Module needs to set a reference value, the reference value of the role of is utilized and the photosensitive sensor by light intensity comparison. When photosensor to light by brighten dark and smaller than the set of reference value, relay is switched on by the module, when the light from dark to light and is larger than the preset reference value module start delay delay, delay completion of the relay is released.

In the relay tube at the output of the time, a photosensitive probe and darken, delay time is a bit, relay has been switched on, arrived at the light time delay relay disconnect.

Work sequence diagram:

Product use:
Automatic detection of light, brightness detection. Through the potentiometer can adjust the brightness detection valve point, and with built-in relay or buzzer alarm and delay function, can do all kinds of light detection alarm, light controlled time delay switch, and the brightness detection switch, can control all kinds of street lamps, night automatically opened, daytime automatically etinguished and automatic car headlights, stage lights, LED lights, traffic detection switch, products are delay adjustable light sensitivity adjustable function, light sensor without blinking.
Module features:
1 imported high performance and high quality delay chip and sensor trigger chip design;
2 with anti - power supply connected to anti - protection diodes, effective protection of products;
ThreeCan do the use of light detection alarm;
4 has the sensor sensitivity adjustment potentiometer and the time delay adjustment potentiometer, effectively solves the problem of flicker;
5 direct control of large current load;

Technical parameter:

Maimum relay load: 10A 220V or 10A 30V (less than that required)
Delay time: 1-180 seconds(can also be customized for other time range, please contact the seller)

PCB board size: 60mm 76mm20mm long and wide high

Module instruction:
1 this module uses the photosensitive resistance to carry on the detection of the light intensity, generally used to detect the brightness of the surrounding environment of the light;
. when the detected light intensity is lower than the set threshold, relay, when the environmental light is higher than the threshold, the relay is switched off;
3 if you need the alarm, no need for the relay output, just replace the buzzer can be;
4. Photosensitive resistance of the installation location is very important, if the lights or stage lighting control, can not be put in can feel the need to control the lights, or photosensitive resistance will feel light will enable relay to disconnect, will be circular light the lamp.
5. After the connection, need to adjust light induction in the practical application environment, car headlights, in tunnel regulation dynamic automatic light, delay is generally 5-10 seconds, the street lamp control delay generally transferred directly to the longest time of 180 seconds.
Delivery list:
