A method for estimating a mapping of the concentration of an analyte in an environment uses sensors distributed in the environment. Each sensor generates a measurement of the analyte concentration at various measurement instants, which measurements are carried out by each sensor at each measurement instant, forming an observation vector, each term of which corresponds to a measurement arising from a sensor. The environment is spatially meshed with a plurality of mesh cells. The analyte concentration at each mesh cell, at each measurement instant, forms a “state vector,” each term of which corresponds to an analyte concentration in a mesh cell. A “global bias” is determined and used to correct the state vector to obtain a “debiased state vector.” The state vector is also corrected by a local correction vector as a function of a correction vector.

Heating, ventilation and air conditioning (HVAC) equipments are used to control the indoor climate and thereby control comfort. Most homes and offices are normally equipped with just a sensor to show the temperature level. It is rare to find humidity sensors and temperature sensors in every room in homes and offices so controlling the environment locally is not possible. Air quality, another parameter that influences comfort, is measured by the presence of volatile organic compounds or particles that can now be identified using more sophisticated monitors. An invention is described here that will make it easy and affordable to measure and control the temperature, relative humidity and air quality using a smart phone, that is commonplace now, thereby controlling the comfort level. 1.
