DFRobot_Ambient_Light_Sensor_(SKU_DFR0026_)

Introduction

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

1. Signal Output
2. GND
3. Power

Connection Diagram

Sample Code

void setup()
{
  Serial.begin(9600); // open serial port, set the baud rate to 9600 bps
}
void loop()
{
      int val;
      val=analogRead(0);   //connect grayscale sensor to Analog 0
      Serial.println(val,DEC);//print the value to serial
      delay(100);
}
