10-year battery lifetime

Turn off noise or set office hours (i.e 7AM-5PM Mon-Fri) to get more than 10 years battery lifetime.


Six sensors

CO2, Temperature, Relative Humidity, Pressure, Noise, Light (lux).


Virtual Sensors

Virus Risk, Occupancy.



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

IAQ sensor specifications

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.
