Room based weather station. It's a SenseHat module sitting directly ontop of a Raspberry Pi 3.
Temperature, humidity, and pressure are sampled each second with five minutes averages being saved.
Error bars are one standard deviation away from the mean five minute value.
The sensor sits directly on the Pi CPU which causes problems with accuracy.
The code takes CPU temperature into account, which makes the temperature more precise but nothing can be done about accuracy.
Unless the Sensehat is moved off of the Pi, which is in the process of being done.
Date ranges can also be entered (in the format shown) to trim the data, or left blank for the entire sample to be used.
