Here you can see data collected by my two Raspberry Pi 4 and a Wemos D1 Mini.
Raspberry Pi / D1 Mini – „weather station“
> multi chart
> single charts
> matlab visualization
Data is read in 5 minute intervals by a cronjob, then rendered via the thingspeak API.
To measure temperature, humidity and air pressure, I am using a BME280.
