The LDR (Light Dependent Resistor) Light Sensor Module is a photosensitive sensor used to detect ambient light intensity. It combines an LDR with an LM393 comparator, providing both analog and digital outputs for light-based automation and sensing projects.

The module typically includes an LDR sensor, LM393 comparator circuit, and a potentiometer for adjusting sensitivity. It provides both analog output (AO) for variable light levels and digital output (DO) for threshold-based detection, making it easy to interface with microcontrollers such as Arduino, ESP32, and Raspberry Pi.

Key Features:

  • Detects ambient light intensity using Light Dependent Resistor (LDR)
  • Resistance changes based on light level (dark = high resistance, bright = low resistance)
  • Provides both analog (AO) and digital (DO) output signals
  • Built-in LM393 comparator IC for stable digital output
  • Adjustable sensitivity using onboard potentiometer
  • Operates on 3.3V – 5V DC supply
  • Low power consumption and cost-effective design
  • Fast response to changes in light conditions
  • Easy integration with Arduino, ESP32, Raspberry Pi, and other microcontrollers

Packing List Includes:

  • 1 × LDR Light Sensor Module
