Wiring Diagram

Other Preparation Work

	Before downloading the program, you must know the reference voltage of the analog port.If your board supply voltage is 3.3V, then you need change voltageRef which is in sample code from 5.000 rto 3.300,If your board supply voltage is 5.0V,then set voltageRef to 5.000。If you want a higher precision,Then you need to measure the voltage of the IOREF port and set that voltage to as voltageRef .

#include<DFRobotHighTemperatureSensor.h>

const float voltageRef = 5.000; //Set reference voltage,you need test your IOREF voltage.
//const float voltageRef = 3.300;
int HighTemperaturePin = A0;    //Setting pin
DFRobotHighTemperature PT100 = DFRobotHighTemperature(voltageRef); //Define an PT100 object

void setup(void) {
  Serial.begin(9600);

void loop(void) {
  int temperature = PT100.readTemperature(HighTemperaturePin);  //Get temperature
  Serial.print("temperature:  ");
  Serial.print(temperature);
  Serial.println("  ^C");
  delay(1000); //just here to slow down the output so it is easier to read
}
