XH-M131 Photosensitive Relay Module

Introduction

This module can be used for light detection and brightness detection, with power indicator lamp and relay indicator.
It has four M3 screw mounting holes, which greatly facilitates installation.

The board can adjust the sensitivity of light through the potentiometer. With its own relay, it can be used for various brightness detection control switches,
such as street lights, which can be automatically turned on at night and turned off during the day.
It can also be used for other devices that need automatic control.

Operational Instructions

1. Connect the input terminal to DC 12V. Please pay attention to the positive and negative poles, and do not connect them in reverse. Then the red power indicator light will light up.

2. Connect the output control terminal to the power supply with maximum voltage 250V and current 10A, and connect the load.

3. When the photosensitive probe detects the dimming of light, the switch closes automatically, the load works, and the blue working indicator lights up.
When the light turns on, the relay disconnects, the load stops working, and the working indicator light goes out.

4. If the light detection is not sensitive enough, you can adjust the potentiometer with a screwdriver to achieve the required light detection sensitivity.
