Illuminate your electronic projects with Kunkune’s LM393 Photosensitive Resistance Sensor Module. Expertly designed to detect ambient light intensity, this module is an essential addition to your electronic toolkit, offering both precision and versatility.

LM393Photosensitive Resistance Sensor Module Key Features:

  • Ambient Light Detection: Primarily sensitive to surrounding light, this module is perfect for gauging the brightness of your environment.
  • Intelligent Output: Depending on the ambient light intensity, the module outputs either a high or low DO end, allowing for precise light detection.
  • MCU Compatibility: Connect the DO output directly to your microcontroller to monitor high and low levels, giving you real-time insights into environmental light changes.
  • Relay Module Integration: The DO output can effortlessly drive our relay module, enabling the creation of a light-operated switch.

LM393 Photosensitive Resistance Sensor Module Specifications:

  • Sensor Type: Employs a photosensitive resistance sensor for optimal sensitivity.
  • Operating Voltage: Functions efficiently between 3.5V to 5V.
  • Output Format: Provides a Digital Switch display (0 and 1).
  • Easy Installation: Comes with a fixed bolt hole for hassle-free setup.
  • Compact Design: Features a petite PCB size of 3.2CM x 1.7CM.
