Description
The Relay Light Controlled Module XH-M131 is a versatile module designed for automating light-sensitive systems. By using an LDR (Light Dependent Resistor), this module can detect ambient light levels and activate a relay to control DC or AC appliances accordingly. The light sensitivity threshold can be precisely adjusted using an onboard potentiometer, making it suitable for various lighting automation applications.
Features
- Light-Sensitive Control: Activates the relay based on ambient light levels.
- Adjustable Sensitivity: Fine-tune the light threshold using a potentiometer.
- High Load Capacity: Supports loads up to 10A for AC 250V or DC 30V.
- Dual LED Indicators: Red LED for power status and blue LED for relay activation.
- Versatile Output Terminals: Includes NO (Normally Open), NC (Normally Closed), and COM (Common) terminals.
- Easy Installation: Four M3 mounting holes for secure installation.

Pinout
| Component | Description |
|---|---|
| LDR (Light Dependent Resistor) | Detects ambient light levels and sends signals to activate or deactivate the relay based on light intensity. |
| Relay (10A) | Electromechanical switch capable of controlling high-power devices (up to 10A at AC 250V or DC 30V). |
| Potentiometer | The adjustable resistor is used to fine-tune the light threshold sensitivity for activating the relay. |
| Red LED (Power Indicator) | Indicates the module is powered on when lit. |
| Blue LED (Relay Indicator) | Indicates the relay is active when lit. |
| NO Terminal (Normally Open) | Output terminal that closes the circuit when the relay is active. |
| NC Terminal (Normally Closed) | Output terminal that opens the circuit when the relay is active. |
| COM Terminal (Common) | Common connection point for the relay’s output terminals (NO and NC). |
| 12V Input Terminals | Connects the DC 12V power supply to power the module. |
| PCB Screw Mount Holes | Four M3-sized holes for securely mounting the module onto a surface. |
| Base Circuitry | Includes resistors, capacitors, and transistors for stable operation and signal processing. |
And for the relay:
- VCC: Connect to DC 12V power supply.
- GND: Ground connection.
- COM: Common terminal for the relay.
- NO: Normally Open terminal – closes when relay is active.
- NC: Normally Closed terminal – opens when relay is active.
Applications
- Light Detection: Automates devices based on ambient light levels.
- Brightness Control: Adjusts brightness-based systems such as streetlights.
- Automation Systems: Controls devices to turn on/off automatically based on lighting conditions.
- Home Automation: Ideal for night lights, garden lights, and other lighting systems.
Package Includes
