Graphical Temperature & Humidity Control Unit Using a Raspberry Pi Pico

Raspberry Pi Pico is a cute piece of hardware. It is equipped with a powerful dual-core RP2040 microcontroller that offers 2M (up to 16M) Flash and 264K SRAM memories. Such specifications make it suitable for a variety of hobby and industrial applications.

In this article/video, I used a Pico board, a digital SHTC3 sensor, and a 2.4” colorful TFT display to build a graphical temperature and humidity measurement/control unit that can be used to monitor the home, workplace, indoor garden, devices … etc. The board was also equipped with two Relays that allow the user to set the cooling/heating limits and adjust the parameters in the GUI.

The trickiest part of this project was the Pico code. I used the Pico C/C++ SDK library and invested a significant amount of time in designing the GUI and debugging the code. I should confess it was not an easy task.

To design the schematic and PCB, I used Altium designer 22 and installed the missing component libraries using Altium’s manufacturer part search.
