SKU: FA3041 Tag:
Dimensions 3.5 × 1.5 × 4.5 cm
Operating Voltage

3.3V ~ 5V

Output Type


The  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.

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

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