This tutorial shows how to make a basic logger using WiFi and Adafruit MQTT. It is based on the cheap WeMos (Esp8266) micro controller with an air pressure/temperature and an OLED shield. It is programmed with an simple Arduino sketch and put in a 3D-printed case. I also explain how the altitude is calculated from airpresure. This logger should be doable for beginners, since not much soldering is needed. Enjoy watching!
