Technical Specifications

How to Use

To use the LDR Module, connect the VCC pin to a 3.3V to 5V power source and the GND to ground. Connect the DO pin to a digital input on your microcontroller. The output pin provides a logical high (often corresponding to 5V or 3.3V) in darkness and a logical low (0V) in the presence of light. Adjust the potentiometer to set your desired light threshold. When the ldr module sensor detects that the light intensity exceeds this threshold, the DO pin will output a high signal, which can trigger an external device, such as a relay, to perform an action based on the light condition. Use the ldr module with arduino for seamless integration in DIY projects to explore circuit behaviors and automation.
