Thanks to this, it can be connected to an analog input on an Arduino board and produce a measurement without the need for digital protocols or special libraries. In this article we will see how this sensor works, how to identify its pins, what the basic Arduino connection looks like, and how to read the temperature in the serial monitor with a very simple program.
