Digital LDR Module – 3 Pin (Light Sensor Module)

The Digital LDR Module is a photosensitive sensor designed to detect ambient light intensity. It provides a digital output that switches HIGH in the presence of light and LOW in darkness. The sensitivity of the module can be adjusted using the onboard potentiometer, making it versatile for different applications, such as automatic lighting control and brightness detection.

With its LM393 comparator design, the module ensures accurate light detection and can be easily interfaced with microcontrollers like Arduino, Raspberry Pi, and ESP8266.

🔹 Key Features

✔ Accurate Light Detection with a Built-in LDR (Light Dependent Resistor)
✔ Adjustable Sensitivity via a Blue Potentiometer
✔ Digital Output (0V – 5V) for Easy MCU Integration
✔ Onboard Power & Status LEDs for Easy Monitoring
✔ M3 Mounting Hole for Simple Installation
✔ Compact & Low Power Consumption

📌 How It Works

1️⃣ Light Detection: If ambient light intensity exceeds the set threshold, the module outputs LOW (0V).
2️⃣ Darkness Detection: If light falls below the threshold, the module outputs HIGH (5V).
3️⃣ Microcontroller Integration: The DO (Digital Output) pin can be connected to an MCU to trigger actions based on light levels.
4️⃣ Relay Control: The module can directly drive a relay module for automated lighting systems.
