The KY-018 Photoresistor Module is an analog light intensity sensor that changes resistance based on ambient light levels. It outputs an analog voltage proportional to the light intensity, making it ideal for light-sensing projects with Arduino, ESP32, and other microcontrollers. Easy to interface and operate at 3.3V to 5V.
