Light Dependent Resistor-LDR Module
  • Function: Detects light intensity using a photoresistor (LDR) – resistance decreases as light increases.

  • Sensor Type: Analog light sensor with digital trigger output capability.

  • Operating Voltage: 3.3V – 5V DC – compatible with Arduino, ESP32, Raspberry Pi, and more.

  • Dual Output:

  • Analog Output (AO): Provides variable voltage based on ambient light levels.

  • Digital Output (DO): High/Low signal based on user-defined threshold (set via onboard potentiometer).

  • Adjustable Sensitivity: Onboard potentiometer to tune the light threshold for the digital output.

  • Onboard Indicators: Power LED and digital output status LED for easy debugging and testing.

  • Compact PCB Design: Easy to mount and integrate into light-sensitive automation systems.

  • Quick Response: Fast change in resistance allows real-time detection of light changes.
