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
