The BME280 sensor provides temperature, barometric pressure, and altitude. I have the DHT sensor serving temperature data in celcius and faharenheit. On the BME sensor altitude is reckoned using barometric pressure and sealevel pressure - i didnt want to mess with that because my sensors will be distrubuted.
