Project box, adapted from https://www.thingiverse.com/thing:3194520 by K.C. Budd (phreakmonkey, http://www.phreakmonkey.com).
I changed the layout to additionally fit battery clips, a charging board, a step-up/-down converter board. It is now capable of sending temperature and humidity via WiFi (MQTT) every 20 minutes while being in deep sleep in the meantime.
What you need:
Wemos D1 Mini (or clone), e.g. https://www.amazon.de/gp/product/B0754W6Z2F
18650 battery, e.g. https://www.amazon.
