- Onboard optocoupler isolation relay provides effective protection for the chip, ensuring reliable product performance. - Designed for a 12V power input, this relay board regulator transistor functions as a sensor, enhancing stability and dependability. - Adjustable sensitivity setting allows you to customize the relay threshold using a potentiometer. When the light intensity drops below this threshold, the relay is activated, and it releases when the light is restored. - Incorporates a photoresistor that directly regulates the relay based on light intensity, offering precise control. Applications: - Ideal for automated lighting systems, where it can activate lights based on ambient light levels. - Suitable for security systems, triggering alarms or notifications when light conditions change unexpectedly. - Useful in agricultural settings, allowing for automated control of grow lights based on natural light availability. This product is built for performance and reliability, making it an essential component for various electronic projects and systems.
