Digital LDR Module – 3 Pin

The Digital LDR (Light Dependent Resistor) Module is a compact and efficient sensor used to detect light presence and measure intensity levels. It provides a digital output that switches HIGH or LOW based on the ambient light conditions. The module’s sensitivity can be fine-tuned using the onboard potentiometer, making it suitable for applications like automatic lighting systems, smart home automation, and security devices.

🔹 How It Works

✔ When light intensity is below the threshold – The module outputs LOW (0V)
✔ When light intensity is above the threshold – The module outputs HIGH (5V)
✔ Sensitivity Adjustment – The potentiometer allows fine-tuning of the threshold level
✔ Direct MCU Interface – The digital output (DO) can be connected directly to a microcontroller (e.g., Arduino, ESP32, Raspberry Pi)
✔ Relay Control – Can be used to trigger relays for light-based automation
