- Stable 12V Power Input: Designed specifically for relay board regulator transistors, this module ensures enhanced stability and reliability during operation, making it an essential addition to your projects. - Adjustable Sensitivity: Features a distribution bit sensitivity adjustment. By fine-tuning the potentiometer, you can easily set the relay activation threshold. When light levels drop below this threshold, the relay is triggered; once the threshold is exceeded, the relay will deactivate, providing precise control. - Optocoupler Isolation: Equipped with an onboard optocoupler, this relay module offers effective chip protection, ensuring reliable operation and longevity of the device under various conditions. - Light Intensity Control: Utilizes a photoresistor to directly control the relay based on ambient light intensity, making it ideal for applications that require light-based automation. Applications: 1. Automated Lighting Systems: Ideal for creating automatic lighting solutions in homes or offices that turn on or off based on ambient light levels. 2. Security Systems: Perfect for integrating into alarm systems that activate relays when light conditions change, enhancing security measures. 3. Garden Lighting: Use this module to control garden lights that turn on at dusk and off at dawn, ensuring energy efficiency and convenience. This product is designed for easy integration into various electronic projects, making it suitable for hobbyists and professionals alike. Its compact size and robust performance ensure that it meets a wide range of needs effectively.
