Photo Cell Sensor

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
