Operational Environment (Temperature, Relative Humidity): 32°F to 113°F (0 oC to 45 °C) / 5% - 85% (non-condensing)

Weight: ~2.9 oz (~84 g) with batteries

Dimensions: 3.17 x 3.17 x 1.04 in
(80.5 x 80.5 x 26.6 mm)

Frequency band: 865-870 / 902-928 MHz depending on the region

Power: 2 x Lithium AA batteries

Connectivity: Airthings SmartLink 

Noise Indicator samples ambient sound less than 1% duty cycle and measures sound pressure level only, no privacy concern.

Firmware updates are automatically downloaded and installed over the air (OTA) via the Space Hub

Sensor sampling interval: 5 min default and 2.5 min optional. Office hours set on building level:  Outside office hours +1 hour before and after, noise sensor is turned off and  CO₂ interval is set to hourly. In addition,  humidity, pressure, and light are reduced to 5 min interval regardless of sensor sampling interval setting. 

Temperature / Humidity:

Temperature Accuracy: ± 0.2℃ /± 0.4 F

Humidity Accuracy: ± 2.0 % RH 

Pressure sensor:

Absolute pressure accuracy: ± 30 Pa 

Unit-to-unit pressure accuracy: ± 30 Pa 

CO₂ sensor:

NDIR Sensor (Non-Dispersive Infra-Red):  Measurement range 400 – 5000 ppm Accuracy ±50 ppm ±5% within 10 – 35 °C / 50 - 95 °F and 0 – 80%RH, after initial calibration time of 7 days. Self-calibrated using an automatic baseline algorithm that updates once a week. 

Light sensor:

Light sensor is measured in received luminous flux per unit area, also known as  Lux. 

Noise sensor:

Ambient sound is sampled at 1% duty cycle and presented as sound pressure level in dB (adjusted to human ear hearing profile - A-weighted, dBA).  

Virtual sensors:

Virus Risk, Occupancy. Please consult web dashboard for latest.
