ENVEA - Model Cairnet 2020 -Autonomous Networks of Sensor-Based Mini-Stations
Cairnet® device is a real-time standalone and networkable air-monitoring station containing up to 6 Cairsens® microsensors and cellular communication within a waterproof enclosure. Thanks to its integrated manifold allowing a dynamic sampling, the measures are accurate and reliable. Electronic compounds are sealed & protected from moisture and corrosive ambient air.
Compact, easily deployable and autonomous thanks to its solar panels and battery, Cairnet® enables you to cost-effectively monitor dust and gas and gives a complete picture of the environmental impact of your operations.
It offers unprecedented flexibility in producing accurate and dynamic air quality measurements across a broad range of industries and applications.
- Odor monitoring: WWTP, recycling, pulp and paper manufacturing, sewerage treatment facilities, refineries
- Indoor and outdoor air quality monitoring: smart cities, road-side & tunnels, schools, airports, ship terminals…
- Process leak detection and monitoring of fugitive emissions: quarries, storage facilities, mines, manufacturing plants
- Forecasting of industrial fence line emissions
- Environmental impact assessments
- Health and safety: mines, industrial sites, construction
- Mapping and modelling pollution sources
- Real time continuous measurement and monitoring of up to 6 gaseous and particulate pollutants simultaneously, among: H2S/CH4S, NH3, nmVOC, O3/NO2, NO2, CO, SO2, PM, plus environmental parameters: temperature, relative humidity and pressure.
- Plug & Play Network: no manual intervention, automatic detection, linking and configuration of the network (Cairsens® / Cairnet® / Caircloud®)
- Very high sensitivity to capture low level gas concentrations (down to ppb)
- Modular, 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 renewed with new ones
- Ability to change the set of pollutants being monitored at any time
- Advanced remote diagnosis with real tracking state of life
- Possibility to realize hybrid AQMS networks (reference stations & mini-stations)
- Operating cost savings: process adjustment & Improvement of local communication (neighbors & authorities)
- Cost-effective solution for air quality monitoring
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.
- Every Cairnet measurement point consists of:
- Solar panel and its battery
- Wireless communication module
- Weather protection enclosure including up to 6 Cairsens miniature sensors, each measuring one or two pollutants. The sensors are to be selected from the list, function of your specific requirements.
