Version 2 of a previously made Thermometer project.

Here’s something useful: A DIY thermometer made completely from scratch using a custom PCB and a couple of 3D-printed parts.

The DS18B20 temperature sensor probe and the TTGO T-display board form the project’s core, and we have incorporated a lithium cell circuit onboard to power the circuit. The DS18B20 temperature sensor measures the temperature, which is subsequently shown on the TTGO Board’s display.

This article covers the entire build process of this project, so let’s get started.
