Autonomous networks of sensor-based mini-stations

Cairnet® 2015

Real-time standalone and networkable air-monitoring station containing up to four Cairsens® microsensors and cellular communication within a waterproof & solar powered enclosure

Following in real-time any given pollutant emissions data directly from your office, via your computer, smartphone or tablet? All the data centralized in the Cloud, with minimum operating costs (no maintenance, no visit on site to retrieve the data…)? Cairnet is made for you.

Cairnet® provides optimal coverage and measurement of air pollution over a vast area with centralized data management in the cloud, via the Caircloud® application

Real-time monitoring and alerts of the most common types of pollutants: H₂S / CH₄S, NH₃, nmVOC, O₃ / NO₂, NO₂, CO, SO₂, PM10 & PM2.5 particulates
Very high sensitivity to capture low level gas concentrations (down to ppb)
Provides reliable measurement data at a fraction of the cost of reference method analyzers
Evolutive, easy to use, easy to move: no cables or complicated installation, just set up and move to different locations on your site as needed

Cairnet^® requires only annual maintenance, when sensors should be replaced with new ones
Ability to change the set of pollutants being monitored at any time (excepting dust)
The Cairsens^® sensors are manufactured in France and are calibrated in our metrological laboratory using Standard Reference AQMS monitors. No need for re-calibration (1 year lifetime). They are delivered with a calibration certificate.

Embedded measurement of temperature, relative humidity and pressure
Possibility to realize hybrid AQMS networks (reference stations & mini-stations)
Measurements meet European directive 2008/50/EC

Independent reviewers, including the European JRC (Joint Research Council) and the US-EPA, have determined the accuracy, linearity, limits of detection and precision of Cairsens^® as very good when compared with reference devices. Further studies with NASA have shown very good agreement with reference measurements.

Leak detection and monitoring of fugitive emissions: quarries, storage facilities, mines, manufacturing plants
Odor monitoring: WWTP, recycling, pulp and paper manufacturing, sewerage treatment facilities, refineries

Forecasting of industrial fence line emissions
Indoor and outdoor air quality monitoring: smart cities, road-side & tunnels, schools, airports, ship terminals…
Health and safety: mines, industrial sites, construction

Providing data for air dispersion modelling
Cairnet monitoring systems can be also used to supplement conventional air quality stations by offering additional measurement points and area coverage.
