XH-M131 Photoresistor Module YFUSET 12V Light-Control Relay 6pcs

Description

Product Overview

The XH-M131 photoresistor module, manufactured by YFUSET, is engineered to deliver precise light detection and automatic brightness control across a wide range of industrial and scientific applications. Powered by a stable 12V DC source, the module integrates a high‑sensitivity photoresistor with a robust relay that can switch loads from 12V up to 220V, making it suitable for both low‑voltage control circuits and higher‑voltage actuator systems. Its compact dimensions of 53x31x19 mm (approximately 2.09×1.22×0.75 inches) and lightweight construction (about 20 g) allow it to fit into tight panel spaces while maintaining excellent thermal performance. The module includes four M3‑size screw mounting holes, providing a secure and repeatable installation method on standard DIN rails or custom enclosures. Anti‑reverse polarity protection safeguards the circuit against accidental wiring errors, extending the lifespan of both the module and the connected equipment. The package ships with six identical units, enabling quick replacement, inventory stocking, or parallel deployment in multi‑zone lighting systems.

Usage

Designed for versatility, the XH-M131 module excels in environments where ambient light levels directly influence system behavior. In manufacturing facilities, the module can be paired with conveyor‑belt lighting to automatically dim or brighten work‑area illumination based on natural daylight, reducing energy consumption and improving operator comfort. In greenhouse automation, the sensor detects sunlight intensity and triggers supplemental grow lights only when needed, optimizing plant growth while minimizing power usage. The module also integrates seamlessly into HVAC control panels, where it can regulate blower fan speed or damper position in response to external light conditions, contributing to climate‑responsive building management. Its 12V relay output is compatible with a variety of downstream devices, including solenoid valves, indicator lamps, and microcontroller inputs, making it a flexible component for hobbyist projects, prototype development, and full‑scale production systems alike.
