AQMesh (v.3.0)

General Description

The AQMesh (v.3.0) is a wireless air quality device that measures ambient gases, humidity, and atmospheric pressure. The AQM5 measures gases including NO (0-20ppm), NO2 (0-200ppb), O3 (0-200ppb), CO (0-50ppm) and SO2 (0-100ppm). The raw sensor signals are transmitted by GPRS to a secure cloud server where the raw output is processed. Processing includes mathematical processing which deals with cross-gas effects and environmental factors. Data can be accessed through a secure web login.

Principle of Operation

This device incorporates electrochemical gas sensors with a fourth electrode to increase stability and combat drift. Precision is maintained by reducing noise levels in the circuit to a few parts per billion. It also uses proprietary catalyst loading and stack structure to certify steady operation at low concentrations.
