Product Introduction

Analog Temperature Module

The module is based on the thermistor (resistance increases with the ambient temperature

changes) works, a sense of real-time to know the temperature of the surrounding environment changes, we send the data to the analog IO, then come down as long as we go through simple programming will be able to convert the sensor output data Celsius temperature values and displayed, it is still easy to use,It effectively, thereby widely used in gardening, home alarm systems and other devices.

Method of application

And the general temperature sensor is the same, are three-line package, when we use the power cord connected OK signal output into the end on the line, because the module output is an analog signal, we want to signal output terminal connected to the Arguing analog IO on sampling, so as to correctly read the temperature value

Test Code:

double Thermister(int RawADC)

double Temp;

Temp = log(((10240000/RawADC) – 10000));

Temp = 1 / (0.001129148 + (0.000234125 + (0.0000000876741 * Temp * Temp ))* Temp );

Temp = Temp – 273.15;// Convert Kelvin to Celcius

return Temp;

void setup

Serial.begin(9600);

void loop

Serial.print(Thermister(analogRead(0)));

Serial.println(“c”);

delay(500);
