User Guide / How to Use

To use the 5mm LDR Light Sensor Module, connect the 4 pins to your microcontroller. Connect VCC to 3.3V or 5V power, GND to ground, D0 to a digital input pin, and A0 to an analog input pin. Use the built-in potentiometer to adjust the light sensitivity threshold for the digital output. The analog output provides a variable voltage proportional to the light intensity. For Arduino or ESP32 users, read the analog pin to get precise light levels, or use the digital pin for simple on/off detection. Bigyan Project recommends testing the module under different lighting conditions to fine-tune performance for your specific application.
