• 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.

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

Cellular communication characteristics:

• Technology and frequency bands: LTE (1800, 2100, 2600 MHz), WCDMA (800,1700, 2100 MHz), GPRS/Edge (850 MHz, 900 MHz, 1800 MHz, 1900 MHz)
• Regulatory compliance: R&TTE directive 1999/5/EC Japan JRF/JPA – FCC – IC
