Autonomous networks of sensor-based mini-stations
Cairnet®
Cairnet® device is a real-time standalone and networkable air-monitoring station including up to six Cairsens® microsensors. It is powered by solar panels and offers cellular communication.
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.
Real time continuous measurement and monitoring of up to 10 gaseous and particulate pollutants simultaneously, among: H2S/CH4S, NH3, nmVOC, O3+NO2,NO2, CO, SO2, PM10, PM2.5 & PM1
- Measurement of environmental parameters: temperature, relative humidity and pressure
- Plug & Play Network: automatic pairing (Cairsens® / Cairnet® / Caircloud®)
- Dynamic sampling and improved protection against moist and/or corrosive environments
- Optional: Ultrasonic anemometer to measure wind direction and speed. Autonomous
thanks to its integrated solar panel and battery
- Automated data saving (micro SD card) and push : no consequence in case of lost
communication service - Communication frequency and measured data volume adapted automatically to the
autonomy of the station - Very high sensitivity to capture low level gas and particulate concentrations
- Modular, easy to use and move on-site: no cables
- Cairnet® requires only annual maintenance: when sensors should be renewed
- Operating cost savings: process adjustment & Improvement of local communication
(neighbors & authorities) - Possibility to set up hybrid AQMS networks (reference stations & mini-stations)
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.
- 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
- 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.
- Optional: ultrasonic anemometer. If this option is selected, it replaces a Cairsens® sensor
