Ville Salminen has written a nice tutorial over on his blog in which he takes a Raspberry Pi, adds a SenseHAT and then programs it to access the SenseHAT sensors to create a mini-weather station. He uses Flask to create a simple web interface, so there’s plenty to learn here. Read the tutorial here.
I do know if anyone else had problems with the Sense Hat, but the temperature and humidity readings were off. I compared them with calibrated sensors.
Still, The SH is a very useful device and but calibration may be necessary.
