Temperatures, relative humidity and air quality (VOC) over a Power-over-Ethernet network!!!!

Monitor air quality

Often CO2 is measured in office buildings, schools, education and sports facilities for the purpose of need-based ventilation control . However, a drawback with CO2 measurement is that VOC-induced odors are not detected as they have little or no effect on CO2 measurements. 
Although there is a need for ventilation, this condition is not recognized by conventional technology. With this VOC measuring device, on the other hand, indoor air quality can be measured in relation to human perception.
