ESP32 case & temperature sensor case

A modular case that will fit an ESP32-DevKitC and similarly designed ESP32s.

A lot of these types of cases exist, but all of them have the sensor (e.g., SHT31-F) and ESP32 chip in the same case. As I wanted minimal heat leakage to obtain the most accurate readings, I decided to design my own case.

The design is made for an ESP32-DevKitC and similar ESP32s. Check Chapter 1 of the following datasheet for specifics – esp-dev-kits-en-master-esp32.pdf. (Be aware that the design is tight and will not allow “filled out” corners next to the antenna, as some models have.)
 

The case is modular, allowing either just a well-ventilated ESP32 in the main case or an extension that can contain sensors. It is specifically designed to work well with the SHT31-F breakout board, as seen in the following datasheet:

Similar sensors can also fit, and you are free to remix your own gate add-on for a particular temperature sensor. The idea is to have a small gap between the enclosure for the ESP32 and the sensor itself.
