Getting started with the Thermistor NTC 20K 

In this tutorial you will learn how to use this thermistor NTC 2OK  with Arduino Uno. The room temperature will be displayed on the serial monitor.

Hardware required

  • Arduino UNO
  • Thermistor 20k NTC
  • Jumper wires
  • Resistor 20k
  • Breadboard

How a thermistor NTC Works

 Thermistors are variable resistors that change their resistance with temperature. They are classified by the way their resistance responds to temperature changes. In Negative Temperature Coefficient (NTC) thermistors, resistance decreases with an increase in temperature. The value of the resistor should be roughly equal to the resistance of your thermistor. In this case, the resistance of my thermistor is 20K Ohms, so my resistor is also 20K Ohms.

Connecting the Hardware

Upload the sample sketch

int ThermistorPin = 0;

int Vo;

float R1 = 10000;

float logR2, R2, T;

float c1 = 1.009249522e-03,

c2 = 2.378405444e-04,

c3 = 2.019202697e-07;

void setup() {

Serial.begin(9600);

}

void loop() {

Vo = analogRead(ThermistorPin);

R2 = R1 * (1023.0 / (float)Vo – 1.0);

logR2 = log(R2);

T = (1.0 / (c1 + c2*logR2 + c3*logR2*logR2*logR2));

T = T – 273.15;

//T = (T * 9.0)/ 5.0 + 32.0;

Serial.print(“Temperature: “);

Serial.print(T);

Serial.println(” C”);

delay(500);

}

Testing the circuit

Upload the program to the Arduino board and then open the serial monitor.If it works correctly you should get the room temperature on the serial monitor.
