2 12V automatic headlight sensor, adjustable in the dark when open lights, more dark lights bright headlights.

Note: This module is suitable for all domestic and imported cars, sales information bar above only can choose several models, there is no way to fit into the modified models one by one tick, so riders were misunderstood.

Brief introduction to functions:According to the variation of eternal light automatically switch lights, driving in the car environment light becomes dark to a certain etent, module automatically turn on the lights. When the vehicle eternal environment light to a certain etent, will automatically turn off the lights.

Question 1: whether the installation of this module will affect the switch of the original car lights?

can't This module and the original car switch is a parallel relationship, even if the module is broken, it will not affect the use of the original car switch.

Question 2: evening meeting the photoreceptor head illuminated, my light will not automatically shut?

can't Module with delay function, when crossing optical head light although into lighting countdown, once after crossing into dark places, the countdown is reset.

Question 3: where is the module installed?

Module installed in the bottom of the steering wheel, where you can find the need to meet the line.

Question 4: light probe where appropriate?

Placed in front of the instrument panel and the front windshield, the most ideal angle is the probe toward the top 75.

Question 5: lamp relay positive and negative polarity line how to find?

Using the universal meter, the voltage change of the wire harness under the direction of the steering wheel is tested to judge the control mode of the lamp.

Headlight switch off, the line voltage is 12V, the switch turns into 0V, such a negative control of the line (the vast majority of cars are this control mode).

Headlight switch off, the line voltage is 0V, the switch turns to 12V, so the line cathode control mode

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;

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:
The default delivery as the following parts, optical delay module 1,With 4P 50cm long lead photosensitive resistance 1.
