Light-dependent resistor (LDR) analog light sensor module

Connection Types

Overview

The photosensitive resistance sensor module uses a light-dependent resistor (LDR) to detect ambient light levels.

The module features:

  • Photoresistor (light-dependent resistor)
  • Analog output (voltage varies with light intensity)
  • Digital output with adjustable threshold (via potentiometer)
  • Operating voltage: 3.3V-5V
  • Detection range: varies with ambient light
  • Quick response time
  • Wide sensing range
  • Onboard LED indicator
  • Uses LM393 comparator for triggering digital output

Configuration Notes

Probably supported through GPIO Binary Sensor component.

Analog output is not exposed by default.
