I am having issues with Enviro HAT humidity and temperature sensors. I wonder if mine is defected or if I am missing something on how to use it. It is not snapped on Raspberry PI but connected by jumper wires.
1) The first humidity reading is often (not always) more than 90, the second and so on drops down to 30-40
2) In the same room 2 minutes apart humidity value can change up to 15 points. For example, first reading - 42, second - 27
3) Temperature value drops much below real value if humidity grows. For example, in the same room with 22C/40% humidity, if humidifier is running, next reading it 10 minutes will show 16C/55% humidity
Do you have any idea why?
