XH-M131 12V Light Control Relay Module Switch Price in Bangladesh

The XH-M131 12V Light Control Relay Module Switch is a compact automatic switching module designed to control electrical loads according to changes in surrounding light conditions. Instead of manually turning a connected light or device on and off, the module can use an optical sensing circuit to detect changes in ambient brightness and control its relay output accordingly.

This type of light-control module is useful for projects where automatic operation is preferred. It can be used for automatic lamps, night-light systems, display lighting, small automation projects, indicator systems, and other applications where a relay needs to respond to environmental light conditions.

The module operates from a 12V DC supply, making it convenient for many low-voltage lighting and automation systems. Its relay-based output also allows a control circuit to switch a separate electrical load without requiring the load itself to be directly driven by the sensor electronics.

For hobbyists and electronics learners, the XH-M131 provides a simple way to experiment with light-sensitive switching without designing a complete light-detection and relay-control circuit from individual components.

What is a Light-Control Relay Module?

A light-control relay module is an electronic switching device that detects the surrounding light level and changes the state of a relay according to a preset or designed threshold. In practical applications, this allows a lamp or other connected load to operate automatically when the environment becomes sufficiently bright or dark.

The sensor section detects ambient illumination, while the control circuit processes the sensor signal and operates the relay. The relay then provides an electrically controlled switching interface for the connected load.

Technical Specifications

Note: Specifications and adjustment arrangements can vary between XH-M131 board versions and manufacturers. Check the markings on the supplied module before final installation.

Working Principle

The XH-M131 uses a light-sensing circuit to monitor the surrounding illumination. When the detected light level changes around the module’s switching threshold, the control circuit changes the state of the relay.

The relay acts as an electrically controlled switch. Depending on the module configuration, the relay contacts can be used to control an appropriate external load. This makes the module useful for applications where a light source should operate automatically according to environmental brightness.

Because the module itself is powered from a 12V DC source, it is particularly convenient for low-voltage lighting and automation projects.

Applications

The XH-M131 12V Light Control Relay Module can be used in various electronics and automation projects, including:

• Automatic night-light systems
• Automatic LED lighting
• Light-sensitive lamp controllers
• Small 12V lighting systems
• Cabinet and display lighting
• DIY home automation projects
• Electronics laboratory experiments
• Educational light-sensing projects
• Automatic indicator systems
• Light-dependent switching circuits
• Battery-powered lighting projects
• Custom automation equipment

Advantages

One of the main advantages of the XH-M131 is its straightforward design. It combines light detection and relay switching in a single module, reducing the number of separate circuit stages required for a basic automatic lighting project.

Its 12V operation also makes it suitable for many commonly available DC lighting and control systems. The relay output provides a convenient switching interface, while the compact PCB format makes it easier to integrate into custom projects and enclosures.

For students and hobbyists, it can also be useful as a ready-made example of how sensors, control circuits, and electromechanical switching can work together.

Limitations

The XH-M131 should be used within the electrical limits of its relay contacts and module circuitry. The exact relay contact rating should be checked on the supplied board before connecting a load.

The module is intended for light-based switching and should not be treated as a precision light-measurement instrument. Ambient light conditions, sensor placement, reflections, and the surrounding environment can influence switching behavior.

For high-voltage AC loads, appropriate electrical protection, insulation, enclosure design, and qualified installation are essential.

Installation / Usage Tips

Use a suitable 12V DC power source that matches the module’s requirements. Position the light-sensing portion where it can detect the intended ambient light level without being directly affected by the controlled lamp unless that behavior is specifically desired.

Before connecting an external load, identify the relay terminals and verify the relay’s contact rating. For mains-powered equipment, use proper isolation and safety precautions rather than treating the module as a complete mains-safety system.

For reliable automatic lighting, mount the sensor away from excessive heat, water, moisture, and strong unintended light sources.

Why Choose the XH-M131?

The XH-M131 is a practical choice for users who need a compact 12V automatic light-control solution without building a complete sensor and relay circuit from scratch. Its combination of light detection and relay switching makes it suitable for a wide range of hobby, educational, and automation applications.
