“This will guide you trough making a simple weather station with good accuracy.
Here we use a ESP8266 WIFI development board to connect the sensor to the internet to save the data. A lot of flavorous exist and will work and I will use the one I have at home: Homefixer ESP8266
There are many different sensors, but according to http://www.kandrsmith.org/RJS/Misc/Hygrometers/calib_many.html the BME280 delivers the best results out of common low-cost hygrometers. (Due to the seller sending me the wrong part, this guide will be using BMP280 but the steps are similar.
The sending of data will be trough MQTT.”
