Code Exemple

	// Demo code for Grove - Temperature Sensor V1.1/1.2
	// Loovee @ 2015-8-26

	#include <math.h>

	const int B = 4275;               // B value of the thermistor
	const int R0 = 100000;            // R0 = 100k
	const int pinTempSensor = A0;     // Grove - Temperature Sensor connect to A0

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

	void loop()
	{
		int a = analogRead(pinTempSensor);

		float R = 1023.0/a-1.0;
		R = R0*R;

		float temperature = 1.0/(log(R/R0)/B+1/298.15)-273.15; // convert to temperature via datasheet

		Serial.print("temperature = ");
		Serial.println(temperature);

		delay(1000);
