- Extended exposure to concentrations below 400 ppm may result in incorrect operation of ABC algorithm and should be avoided.
- Sensor provides readings in the extended range but the accuracy may be lower than that specified in the table.
- The accuracy specification covers environments ranging from 0-50°C and 0-80% RH, and complies with indoor air quality standards ANSI/ASHRAE Standard 62.1-2022 at 25°C.
- Sensor specifications are under controlled laboratory conditions. Field measurements may use localized ambient air quality and historical infiltration rates to enhance the accuracy and baseline readings of NO2 concentrations. This method is effective under typical indoor conditions but may not suit environments with persistently high indoor NO2 levels.
- Using Adaptive Sampling™ in a building with 15 devices, located in a typical North American city with mechanical ventilation and strong wireless signal strength to the gateway.
- During operating hours (9-5, Mon-Fri): one sample per minute for all sensors except particulate matter, and one sample every 10 minutes for particulate matter. Outside of operating hours: one sample every five minutes for all sensors except particulate matter sensor, and one sample every 60 minutes for particulate matter.
- Actual battery life may vary based on usage, environmental conditions, and other factors.
- Cellular is supported in select countries and regions.
