XHM131 Light Control Switch Module — automatic, reliable lighting control Key benefits Automatic brightness control: built-in photoresistor detects ambient light and adjusts switching so lights turn on or off according to real-world conditions. Reduces manual work and unnecessary runtime: automates lighting based on light level, helping simplify operation and reduce energy waste. Robust switching for common lighting loads: integrated relay module handles up to 10 A, allowing direct control of many lighting devices without extra relays. What it does and why you need it Detects ambient light and switches lighting automatically, eliminating the need for manual timers or constant supervision. Provides a simple, dependable way to add dusk-to-dawn or daylight-sensitive control to lighting systems. Suitable for retrofit or new installations where automatic on/off behavior improves convenience, safety, or energy efficiency. Compatibility and performance Power: supports DC 5 V and DC 12 V power supplies. Sensing: photoresistor-based light detection for straightforward, consistent performance. Switching capacity: relay module supports up to 10 A for controlling lighting devices. Integration: designed for easy installation and integration into a variety of lighting systems. Notable attributes Function: light-level sensing with relay-based switching for automatic control. Compatibility: works with standard DC 5 V and 12 V lighting setups and devices within the 10 A relay limit. Ease of use: designed for straightforward wiring and integration into existing control circuits. Reliability: photoresistor sensing and a dedicated relay provide a simple, time-tested approach to automatic lighting control. Typical applications Outdoor security or pathway lighting that needs to switch on at dusk and off at dawn without manual input. Indoor ambient lighting (corridors, stairwells, storage areas) where lights should respond to ambient light levels. Small workshops, garages, or greenhouses where automatic control reduces wasted operation time and simplifies daily routines. Model and color option Model: XHM131 Color option available: XHM131 5V Installation notes Verify supply voltage and wiring before connecting power. Ensure the controlled lighting load does not exceed the relay’s 10 A rating. Designed for straightforward installation into standard lighting control circuits. The XHM131 provides a practical, easy-to-install solution for automatic light control using a photoresistor and a 10 A relay, compatible with DC 5 V and 12 V systems.
