How do Arlo Baby’s air sensors work, and how do I interpret the readings?

Arlo Baby comes with air sensors that measure temperature, relative humidity, and general air quality. The inlet holes for the sensors are located on the right side of Arlo Baby.

Note: Do not cover or obstruct the inlet holes.

You can use the Arlo app to view reports of the temperature, humidity, and air quality detected by the sensors over the past 12 hours, 24 hours, 3 days, and 7 days.

Air Quality Sensor Information

Arlo Baby can measure the level of volatile organic compounds (VOCs) in the room. VOCs are made up of hydrocarbons and can easily become vapors or gases at room temperature. VOCs are released from sources like burning fuel, solvents, paints, glues, air freshener, cleaning supplies, or hair spray.

Arlo Baby can detect overall changes in air quality caused by gases such as these:

  • Iso-butane
  • Carbon monoxide
  • Hydrogen
  • Ethanol
  • Methane

While Arlo Baby’s air quality sensor can detect carbon monoxide, Arlo Baby is not a replacement for a dedicated carbon monoxide or smoke detector.

After you power on Arlo Baby for the first time, it takes about 24 hours for the air quality sensor to finish calibrating and establishing a Normal baseline measurement of your room’s air quality. During this time, place the camera in a well-ventilated area where it has access to fresh air.

If Arlo Baby suddenly reports an Abnormal or Very Abnormal reading, try to discover the reason. The air quality sensor can react strongly to chemicals found in cleaning products, hair spray, or cooking odors. Try opening your doors or windows to let fresh air in. The air quality should go back to normal after a while. If the air quality reading remains Abnormal for a long period of time, make sure that you remove products that might contain VOCs away from Arlo Baby.

If you move Arlo Baby to a new location, you might notice that the air quality readings are Abnormal or Very Abnormal more frequently than before.
