The Atmotube Pro tracks the volatile organic compounds (VOCs) as well as Particulate Matter (PM) pollutants. You don’t need to live in a city with smog problems to need an air quality monitor. Furniture, cheap laminate flooring and carpet are just a few examples of things in your life that can be releasing harmful pollutants into the air you breath.
The Atmotube Pro measures 3.4″ long by 2″ wide by 0.9″ thick and weighing 3.7 (with its carabiner attached). It can track VOCs, PM1 pollutants (having a diameter smaller than 1 micron), PM2.5 pollutants (fine particles), and PM10 pollutants (coarse dust particles), humidity, temperature, atmospheric pressure, and altitude. Its case is made of polycarbonate plastic and aluminum, and it has a Bluetooth Low Energy (BLE 5.0) radio inside for connecting with your smartphone or tablet.
On the top of the Atmotube Pro, there is an aluminum carabiner hole. On the front, there is a small LED that will show different colors depending upon air quality. The LED will glow orange when charging and green when charged, but more importantly, it will glow blue to show good air quality, green to show moderate air quality, yellow to show polluted air quality, orange to show very polluted air quality, and red to show severely polluted air quality. You can activate the air quality LED by pressing the large round button under the LED. You’ll note that on the front and sides of the Atmotube Pro, there are holes present to receive air for quality testing.
How does the Atmotube Pro measure air quality?
Loaded with three sensors: a laser-based PM sensor, a MEMS tVOC sensor, and a combined digital sensor for humidity, temperature, and barometric pressure.
There is a tiny fan that pushes the air through several sensor-filled chambers to make the analysis. The data is stored on your smartphone in real time or if you aren’t connected it will store the last 5 days worth of data in the internal memory. There is no maintenance required for the sensors or fan. The noise level of the fan is about 20dB which is rustling leaves. The fan is ON only during the readings, so in 10 min mode, it will be ON for 1 minute and OFF for another 9 minutes.
Digging into how the sensors the sensors work, the PM sensor uses laser scattering and makes use of innovative contamination resistance technology. They claim it should last at least 8 years.
The tVOC sensor uses the conductivity-change of the gas-sensitive MOX semiconductor layers at gas exposure to do the analysis. It’s calibrated using a clean air and gases mix. Since gases act differently at different temperatures/humidity levels, they utilize our humidity & temperature sensor for compensation for tVOC measurements.
Atmotube Pro will provide more accurate results the longer it runs, but will be more accurate after 12 hours after you first power it on.
You’re able to change how often the Atmotube Pro checks the air quality:
Always On = 1 day
5min = 4 days
10min = 8 days
15min = 12 days
You can also contribute your information to the global air quality map, it’s anonymous data, but you can opt out in settings.
The Atmotube Pro will retail for $189, but you can pre-order it now for $131 here. Shipping will happen in April 2019.
