CONVERT HUMIDITY TO RELATIVE HUMIDITY BLUETOOTH

In the formula below, temperature (T) is expressed in degrees Celsius, relative humidity (rh) is expressed in %, and e is the base of natural logarithms 2.71828 :Ībsolute Humidity (grams/m 3) = 6.112 × e^ × rh × 18.02Ībsolute Humidity (grams/m 3) = 6.112 × e^ × rh × 2.1674 Simple question, which is more than can be said for the answer. Using the ideal gas law, the calculation of absolute humidity from temperature and relative humidity requires an added algorithm that generates saturation vapor pressure as a function of temperature, which complicates things a bit.įormula for calculating absolute humidity But when I do, I always end up asking myself if the air outside has more or less water vapor in it than the air inside. I find this indoor-outdoor thing fascinating for some reason and revel in looking at the numbers. In the photo, the top right quadrant of the display shows temperature and relative humidity for outdoors (6.2☌/94%) and indoors (21.6☌/55%). I have a digital weather station with a wireless outdoor sensor. Ventus W636 Weather Station with outdoor sensor
