  It is a DC 12V light control delay module. Before the module works, it needs to be set-a reference value. The function of this reference value is used to compare with the light intensity of the light sensor.
  1>.Adjustable sensitivity of light sensor
  2>.Adjustable output delay time
  3>.Repeatable trigger delay time can be reset
  4>.Support delayed connection function
  1>.Product Name:DC 12V Light Control Delay Module
  2>.Working Voltage:DC 12V
  3>.Working Current:35mA
  4>.Delay Range:0.5~35 seconds (adjustable)
  5>.Work Temperature:-25℃~85℃
  6>.Work Humidity:5%~95%RH
4.Sensor Working Display:
  1>.When the light sensor senses that the light changes from bright to dark and is less than the set reference value,the module relay is switched on.
  2>.When the light sensor senses that the light changes from dark to bright and is greater than the set reference value,the module starts the delayed output,and the relay is released after the delay.
  3>.In the time of the relay delay output,when the light sensor enters the dark place again,the delay time is reset.
5.Pin Description:
Working status indicator
When the relay is connected,the light is on, when the relay is off, the light is off.
Sensitivity adjustment
1. Turn clockwise to turn on the light when the outside light is brighter (light up in advance).
2. The voltage value of the white point in [8] can be tested with the help of a multimeter. After powering on [4] and [5], the black meter pen of the multimeter is placed on [5], the red meter pen is placed on the white test point, and the adjustable resistance of [7] is adjusted. Adjust the voltage value according to your preferences, the module default setting voltage value is about 6.5V.
3. The higher the voltage value, the darker the external light will turn on.
4. The lower the voltage value, the brighter the outside light will turn on.
JP2 jump cap
By default, the JP2 jump cap is shorted. The short-circuit jumper light-sensitive probe needs to be continuously in a dark place for more than 2 seconds before the relay is turned on. If there is no continuous dark place for more than 2 seconds, the relay does not turn on. If you want the light sensor to turn on the relay when it is dark, just remove the jumper cap.
Connect the light sensor
The module itself has a sensor. During the installation process, do not pull the light sensor away from the module.
Delay time adjustment
Rotate clockwise to shorten the delay time, counterclockwise to increase the delay time.
