XH-M131 DC 12V Light Control Switch Photoresistor Relay Module

Quality electronics from The Engineer Store, Bengaluru. Fast shipping, 7-day warranty on manufacturing defects, expert support.

Product Overview

The XH-M131 is a compact, intelligent light control module featuring an integrated photoresistor (light sensor) and relay switching mechanism. This DC 12V module automatically detects ambient light levels and triggers relay output, making it ideal for automatic lighting systems, security applications, and smart automation projects.

Key Features

• Automatic Light Detection: Built-in photoresistor (LDR) sensor for ambient light sensing
• DC 12V Operation: Standard voltage compatible with most DIY and industrial systems
• Relay Output: Reliable switching for controlling lights and other AC/DC devices
• Adjustable Sensitivity: Potentiometer for fine-tuning light detection threshold
• Compact Design: Small PCB form factor for easy integration
• Low Power Consumption: Efficient operation suitable for 24/7 applications
