XH-M131 5V Photo-resistor Relay Module
The XH-M131 (5V version) is a light detection relay module that uses a photoresistor (LDR) to detect ambient light levels and automatically control a relay. When the light intensity falls below or exceeds a preset threshold (adjustable via a potentiometer), the relay activates or deactivates an external electrical device.
This module operates on 5V DC, making it ideal for use with Arduino, Raspberry Pi, ESP8266, ESP32, and other microcontrollers for smart lighting, automatic control systems, and home automation projects.
Features:
- 5V Operating Voltage – Compatible with microcontrollers and 5V power supplies
- Automatic Light Control – Activates relay based on ambient light
- High-Power Relay – Supports up to AC 250V 10A / DC 30V 10A
- Adjustable Sensitivity – Fine-tune light threshold via a potentiometer
- Dual Relay Output Modes – NO (Normally Open) & NC (Normally Closed)
- Simple Wiring – VCC, GND, and OUT terminals
- Compact PCB Size – Easy integration into projects
