using the bme680 to measure temperature, pressure, humidity and air quality. the sensor is used to obtain the so-called gas resistance and then calculate an index of air quality (iaq) from a combination of humidity and the gas content readings of the air, optionally temperature could be added too, but omittied in this example. the index is a function of humidity which contributes up to 25% and gas concentrations that contributes up to 75%. see slide1.jpg for details of the iaq index formulation. in this current version only humidity and gas concentrations are used for the index, but adding temperature woudl be straightforward on the basis that temperatures for humans that are too high or low add to the overal air quality index along with humidity and gas concetrations. humidity is measured between 0 - 100% and is universally accepted as being optimal when it is 40% and where in this index the contribution will be 0, but at a humidity reading of 0%, the contribution increases
