Temperature Measurement Tutorial (Part1)

In this project I will show you how the resistance of different materials is used to measure accurate temperatures. The project will include information about NTC thermistors, PT100, Wheatstone bridge, LM35 and DS18B20. And at the end I will show you how to build a simple thermometer. Let's get started!

The video gives you all the information you need to build a simple thermometer. But I will present you my used components, schematics and code in the following steps.

Here is the list of temperature sensors that I used during the tutorial:

Here you can find all the schematics that I used during the video. Feel free to use the thermometer prototype schematic to build your own

Here you can find the Code/Sketch which you need to upload to your Arduino before you can use your homemade thermometer.

You did it. Not only did you learn a lot about resistance temperature sensors but you also made a homemade thermometer!
