Introduction

This photo cell sensor module uses the GL5528 photoresistor to detect the light intensity of environment. An Op-amp LM358 is configured as a “voltage follower” to decease influence of resistance variation when light intensity changes.

Features

  • 2.54mm general interface
  • Wide supply voltage range: 3V–30V
  • 2.0cm x 2.0cm module
  • Application fields widely
