Automatically open the headlights, headlight automatic sensor night / tunnel lighting.

Brief introduction to functions:

When the car runs toThe tunnel or dark place(2 seconds)More afterRelay switch on and turn on the car headlightCar travel toThe tunnel or dark placeLess than 2 seconds relay does not move that does not turn on the headlightsThis prevents the pedestrian bridge, frequent open headlamps,As long asTunnels orDark placerelay(headlight)Has been switched on, out of theTunnelAfter the light of the place, the time delay start(delay time can set their own 1-180S adjustable),Time delay,relayDisconnect, car headlights also disconnected

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 by using the MCU control sensor trigger delay controller;
2 to provide a variety of power input connection, to meet a variety of different needs;
3 with anti - power supply connected to anti - protection diodes, effective protection of products;
4 with a high current voltage regulator, to provide adequate power supply;
5 has the sensor sensitivity adjustment potentiometer and the time delay adjustment potentiometer, effectively solves the problem of flicker;
6 direct control of large current load;
7 can be used to detect the use of light alarm.
Technical parameter:
Power input: 12VDC current: greater than 500mA
Maimum relay load: 30A 220V or 30A 30V (less than that required)
Delay time: 1-180 seconds (can also be customized other time range, please contact the seller)
PCB size: 60mm 76mm
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;
The installation position of the 3. Photosensitive resistance 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.
4. After the connection, need to adjust light induction in the practical application environment, such as automobile headlamps, 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.
