so the new temp/humidity sensor is working well on my homebrew weather station (AHT20 replaced with a SHT45)
the SHT45 is a I2C sensor with a built in heater so i can dry the sensor element so it don't drift
it just needs a 0.1s low heat each cycle if the humidity is above 90%, i read the sensor to run a heat/read cycle then wait 3 minutes before i read the data i publish to the cloud dashboard, that allows enough time for the temperature to stabilise to ambient
