    Analog Grayscale Sensor V2 SKU:DFR0022 Analog Grayscale Sensor V2 Contents     1 Introduction 2 Specification 3 Connection Diagram 4 Sample Code Introduction Here comes DFRobot's new Analog Ambient Light Sensor. Brand new design and much more convenient to use.This module help you to detect the light density and reflect the analog voltage signal back to Arduino controller. You can set the threshold of voltage level to trigger motors, relays or other actuators. Specification    Supply Voltage: 3.3V to 5V Interface: Analog Size:22x30mm 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); }       Powered By DFRobot © 2008-2017
