This is a small box for basic weather station that you can put indoor and have it powered with micro USB. The box size fits Lolin NodeMcu v3 ESP8266 and temperature/humidity/pressure sensor BME280 placed in a separate compartment. To keep the box smaller I have designed it so that you'll need to do a bit of soldering to attach your wires to ESP8266. There is also a reset pinhole and USB cable opening.

To complete the project you can use part of this tutorial: https://www.instructables.com/...

I have also attached my simple code for ESP8266 which reads sensor data and sends them via MQTT to server. On the server side I use Mosquitto broker and Node-RED to process and visualize data on Raspberry PI.
