Light sensor photoresistor GM5516

This light-sensitive resistor is suitable for detecting brightness. Its resistance decreases the more light falls on it and is approx. 5 to 10 kΩ at 10 lux.

Recommended alternative for measuring in lux: BH1750 GY-302 Digital Light Sensor / Light Intensity Sensor with I2C
