In this tutorial, we learn how to interfacing Thermistor with an Arduino. How to get temperature readings from Thermistor and display them in LCD Display.
A thermistor is also known as a thermal resistor that is used to sensing temperature like cold and heat around us. The thermistor is a resistor whose resistor is changed according to change in temperature.
Thermistors are cheap, reliable and respond quickly. They are mainly used for low-temperature range but not for high temperatures.
Thermistors are mainly used in home appliances, for circuit protections, refrigerator, etc.
Components Needed
- Arduino UNO.
- Thermistor.
- 1 KΩ Resistor.
- Jumper Wires.
- Breadboard.
- LCD 16×2 Display.
- Potentiometer.
Circuit Diagram For Thermistor With Arduino
Code for Thermistor With Arduino
Upload the below code and open the serial monitor to view temperature readings.
Output
Now we will display the thermistor temperature readings on an LCD Display. So we connect an LCD 16×2 display and thermistor with Arduino.

Code For Thermistor and LCD Display
Upload the below code and view the output on the LCD Display.
Uses of Thermistor
- Use for circuit protection.
- Uses in home appliances like refrigerator, ovens.
- Digital thermometers.
- Rechargeable batteries.
