Introduction: Thermistor Sensor Module Interface With Arduino
This tutorial teaches the basics on using the Thermistor Sensor Module.
Step 1: Introduction
Thermistor Sensor Module is used to sense temperature and convert it into output signals. It is associated with both analog output pin and digital output pin labelled as AO and DO respectively on the board. Thermistor Sensor Module is made of semiconductor materials. Basically thermistor sensors are mostly Negative Temperature Coefficient (NTC), which means NTC thermistors will have their electrical resistance decreased when subjected to an increase in body temperature. This module has a potentiometer knob that can be adjusted to change the sensitivity of thermistor towards temperature.
- Input Voltage: DC 3.3V to 5V
- Output: Analog and Digital
- Sensitivity Adjustable
- Size: 32mm x 14mm x 5mm
Step 2: Pin Definition
Step 3: Sample Hardware Installation
Step 4: Sample Source Code
To get the result, please download the sample source code attached below and upload it into Arduino.
Step 5: Ways to Open Serial Monitor
Step 6: Result (1)
The readings shown on Serial Monitor when thermistor approaches something warm.
Step 7: Result (2)
The readings shown on Serial Monitor when thermistor is left in a room.
We have a be nice policy.
