AQ Mesh mobile air quality monitor

AQMesh low-cost outdoor air quality monitor



AQMesh is the only commercially available and proven low-cost system for monitoring air quality. The product combines a robust hardware platform with the latest sensor technology and GPRS communication, cloud-based data processing and secure online access. AQMesh pods are manufactured in the UK to the very high quality based on many years of experience of developing environmental monitoring equipment for harsh environments and challenging international standards. This experience has also allowed electronic noise to be reduced in such a way that the best possible sensitivity is achieved from the sensors used. Gases are measured using the latest generation of electrochemical sensors, which allow compensation for environmental factors and sensitivity to 5ppb. Particles are measured using a light scattering optical particle counter, and noise is measured using an omnidirectional electric condenser microphone.

AQMesh parameters available

The product currently measures nitric oxide (NO), nitrogen dioxide (NO2) and ozone (O3) using a new generation of electrochemical sensors. The standard product also measures pod temperature, atmospheric pressure and relative humidity.

Carbon monoxide (CO) and sulphur dioxide (SO2) can also be chosen as optional electrochemical sensors. AQMesh also offers measurement of total particle count, PM2.5 and PM10 using a light-scattering optical particle counter.

Noise is measured using an omnidirectional electric condenser microphone.
