LDR Light Sensor Module

The LDR (Light Dependent Resistor) Module is a compact and efficient sensor used to detect ambient light levels. It is widely used in light-sensitive applications such as automatic lighting, solar garden lights, and smart home automation systems.

This module outputs both analog and digital signals, making it ideal for integration with microcontrollers like Arduino, ESP8266, ESP32, and Raspberry Pi. The onboard LDR sensor changes resistance based on the intensity of light. Bright light causes lower resistance, while darkness causes higher resistance.

With an adjustable sensitivity via the onboard potentiometer, you can fine-tune the trigger level of the digital output, making it suitable for precise light threshold-based actions like turning on a light or closing a curtain automatically.

???? Key Features:

• ✅ Dual Output Signals (Analog & Digital)
  Supports both A0 (analog) for real-time light intensity readings and D0 (digital) for threshold-based triggers.

• ✅ High Sensitivity LDR Sensor
  Detects a wide range of light levels, from dim to bright daylight.

• ✅ Adjustable Trigger Sensitivity
  Onboard potentiometer allows easy calibration of the digital output threshold.

• ✅ LED Indicators
  Power and output status LEDs help with real-time monitoring and debugging.

• ✅ Compact and Easy to Use
  Small, breadboard-friendly size and standard 3-pin interface make integration simple for beginners and experts alike.

• ✅ Low Power Consumption
  Ideal for solar-powered or energy-efficient systems.
