Another temperature / baro sensor based on D1 mini

I designed this tiny sensor case around the popular D1 mini and a BMP280 sensor.

It is a very sturdy case that is held together by 4 bolts M3*8 and features a blind button hole at the back so you can hang it over a nail or screw head.

For indoor use only, as the USB connector is not sealed and the sensor board is exposed (which makes sense for a temperature sensor I guess). And yes, the case also accomodates the necessary internal wiring (not shown in the pictures) :-).

Please note there are different variants of the BMP280 out there (different PCB dimensions). Please verify that you have the matching (6-pin) type.

I use Tasmota as a firmware on the D1 mini and link the sensor to my smart home server.
