What is QSense-Air?

QSense-Air, an Air Quality Sensor provided by Macq is a highly reliable Air Quality, Rain, and Noise sensor that accurately measures the most important gaseous pollutants (NO2, O3, VOC, CO, CO2, SO2, H2S, NH3), particulate matter (PM1 / 2.5 / 10), weather parameters relevant to monitor, estimate, and forecast air quality (air pressure, temperature, humidity, rain), as well as the surrounding noise. It enables you to better understand your environment and control pollution. 

QSense Air

How it works

The data can be accessed locally through Ethernet or transmitted wirelessly to a web-based database. With dual GPRS and 4G LTE connectivity, our QSense-Air ensures heightened data reliability for a dependable analysis of your conditions.

Our QSense-Air's measurement precision relies on sophisticated algorithms enabling parts per billion (ppb) measurements, utilizing electrochemical sensors (exclusive to CO), semiconductors, optics, and analog sensors. These algorithms compensate for ambient conditions and sensor element aging, eliminating the requirement for expensive gas sampling and maintenance equipment.
