Photosensitive Diode Relay Module 5V Light Sensor Switch Board | Automatic Light Detection Relay 10A

Photosensitive Diode Relay Module 5V Light Sensor Switch Board | Automatic Light Detection Relay 10A 

The Photosensitive Diode Relay Module is an automatic light detection switch board designed to control electrical devices based on brightness level. It uses a photodiode sensor to detect light intensity and activates the relay when the brightness crosses the preset threshold.

The module includes an adjustable potentiometer to set the required light level, allowing accurate switching for different lighting conditions. Compared to LDR-based modules, the photodiode sensor provides better directional light detection, making it suitable for applications where light comes from a specific direction.
