This module is sensitive to light in the dark or when no light and relay
Sensor probe photoresistors and photodiodes have two kinds, the default hair is light sensitive resistor type, you need to make a single shot photodiode photodiode probe.
 
Usage:
Light detection and brightness detection, detection can be adjusted via potentiometer brightness valve point comes relays, and do all kinds of brightness detection switch, you can control all kinds of street lights or car lights automatically turn on at night, during the day and automatically turns off and car supplies control and automation equipment.
Product life and aging tests, automatically pass off time is adjustable timing precision.

Module Features:
1.Imports of high-performance quality delay chip design;
2 offers a variety of power input wiring to meet the various needs, the default shipping is first;
3. Protection against power reverse protection diode, the effective protection of the product;
4 with the relay on-time and off-time adjustable function;
5 can directly control high current loads;
 
Technical parameters:
Supply voltage: 6-14V
Current:> 500mA
The maximum load of the relay: 220V 10A or 30V 10A (less than this requirement can be used)
:1-190 seconds delay time ( default is 1-190 seconds adjustable time ranges )

Product description:
1. Energized relay that pull, pull potentiometer adjustable time to disconnect potentiometer adjustable off time, then repeatedly pull disconnect ... 220V or other power control, do not cut the jumper cap plug, otherwise it will burn module.
