KY-018 Photoresistor sensor module is used to measure light intensity. It can determine the presence or absence of light. This module consists of a photoresistor and a 10 kΩ in-line resistor. The photoresistor’s resistance will decrease in the presence of light and increase in the absence of it. The output is analog and determines the intensity of light.
Specifications:
- Operating voltage: 3.3~5v
- Output Type: Analog
