Introduction

The DFRobot Grayscale Sensor is an analog sensor. It is a special sensor with arduino expansion boards. The Gray-scale sensor interface uses PH 2.0 socket. The power supply needs the same controller, typically for 3.3V or 5V.

Specification

• Analog Sensor
• PH 2.0 socket
• Special sensor with Arduino expansion boards
• Pins Description: 1--Output; 2--Ground; 3--Power supply
• Input Voltage: 3.3V/5V
• Operating Temperature: 0-70°C

Note: the product is NOT waterproof and dustproof; the detection accuracy will be affected by the light brightness of the environment and light reflectance of the material the sensor detects.

Pin Definition

The definition of gray-scale sensor pin is

1. Signal Output
2. GND
3. Power

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);
}
