Video Tutorial: BME820 Environmental Sensor and MQTT under Micropython
February 20, 2018
This week we’re starting to make our Micropython powered Wemos D1 truly useful with a sensor and data collection. We’ll wire up a BME280 sensor which measures temperature, humidity and air pressure. After we know it works, we’ll use Wifi and MQTT to send the data to a website for viewing.

I liked the idea of a sub-300$ weather station, that did exactly what I wanted. Yea you can get an ok Oregon Scientific weather station for a bit over 200$, but thats not as cool as making your own (and its not linuxed powered). Anyways I’m just going to post part costs & part name (a few links, the generic stuff is easy though). Most of this stuff is “old tech” so you probably have some of it laying around, so you could get away with it for even cheaper.
