DFRobot Ambient Light Sensor

The DFRobot Ambient Light Sensor works with Cds Photoresistor and allows you to have a DC

Voltage output depending on the brightness of lights. Dark has a low value. The sensor can be used to

detect the intensity of ambient light.

Specification

• Detects ambient light density

• Works with Cds Photoresistor

• Analog voltage output: 0 to 5 Vdc

• Suitable supply voltage: +3 to 5Vdc

• Interface with microcontrollers and logic circuits

• Standard 3-pin PCB connector

• Analog sensors

• Uses PH 2.0 socket

• Special sensor with Arduino expansion boards

Pin Definition

The definition of ambient light sensor pin is:

• Signal Output

• GND
