AQMesh mobile air quality monitor

AQMesh low-cost smart 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.

  • Measures gases NO, NO2, NOx, O3, CO, SO2 and H2S using the latest generation of electrochemical sensors
  • Optional CO2 monitoring with a NDIR sensor
  • Measures particulates PM1, PM2.5, PM10 and TPC with a light-scattering optical particle counter
  • Measures relative humidity, pod temperature, atmospheric pressure and noise
  • Optional meteorological sensor for wind speed and direction measurement
  • Various power options, including battery and bespoke solar pack
  • Wireless communications
  • Secure online data access
  • Extensively proven performance and in the field accuracy against reference equipment
  • Global supply and support
