The KY-018 Photoresistor module is used to measure light intensity. The 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.

Compatible with many popular microcontrollers like Arduino, ESP32 and others.

KY-018 SPECIFICATIONS

This module consists of a photoresistor, a 10 kΩ in-line resistor and 3 male header pins.

Operating Voltage 3.3V ~ 5V
Output Type Analog

CONNECTION DIAGRAM

Connect the Power line (middle) and ground (-) to +5 and GND respectively. Connect signal (S) to pin A2 on the Arduino.
