Wearable or portable devices are not so often considered important in order to protect yourself from air pollution. Most ads claim that we spend 90% indoors and we need an indoor AQ Monitor which is true but we also move around we go to work or we visit friends and family who don’t have an AQM in their house or simple they are not aware of the problem.
Here comes the new Atmotube PRO a small portable AQM equipped with a laser scattering PM1, PM2.5 and PM10 sensor. It also features a VOC sensor and a complete weather station with humidity, temperature and barometric sensor.
It is a great device to spark a conversation with someone about air pollution.
- Laser Scattering Particulate Matter PM1, PM2.5 and PM10 sensor (aka PMx)
- Temperature/ Humidity / Barometric Sensor
- Bluetooth 5.0
- USB Type-C port & Cable
- up to 1 week Battery
- RGB LED
We can clearly see the bold design of the app with big font size and easy to read information. Elderly will definitely enjoy the simplicity of the app. One of my favourite parts of the app is the Comfort Zone info-graph as I am obsessed with Humidity. You can always pinch on the Sheets and reveal more information, for example, if you pinch the Air Quality Score and VOC sheet you will access all the current and previous measurements. The same for the Barometer and Altimeter and Temperature & Humidity Sheets.
The app has a tone of settings and it is designed in a way to please even the most advanced user like myself and it even offers the ability to export a .csv file with all the measurements your monitor has taken. Great for field studies.
If you use macOS you can simple share the measurements via AirDrop and Windows user can email or upload to DropBox the measurements as easily as macOS user.
You can download and try the app even without having a device.
The device is very small 8.5x5x2.1cm, it weighs 105g and it can easily be placed everywhere, inside a car (in case you still have one), on a bike — thanks to the carabiner hook —, in your bedroom, you name it… I have it attached to my messenger bag when I got to work and on my computer desk when I am at home.
The device can hold up a charge up to 12 days depending on the settings and how often it takes measurements, for example, you can turn on the PMx sensor in continuous mode and it will last for 1 day, if you choose to take measurements every 5 min then it will last for 4 days and so on… 10 min (8 days), 15 min (12 days). The Always ON option is suitable while you are on the go and the 5min option for an indoor environment since the air quality will probably not change that often.
I carry it with me every day and I can’t wait to go to new places and discover what I am breathing.
The PMx sensor is vulnerable to high humidity — like all light scattering sensors — this is an issue for those who live near the coast, which means if the RH rises above ~80% the measurements might be slightly different.
When you charge the device the Temperature/ Humidity sensor goes off because the internal temperature of the electronic components and the battery rise and in order to protect you from misinformation the info is not available temporally.
They use the BME280 sensor which is widely known as a good sensor for Temperature, Humidity and Barometric measurements and they have chosen a Sensirion gas sensor for the VOCs because they weren’t satisfied on how the commonly BME680 4 in 1 sensor measures gas. I have heard from other engineers that the BME680 is a very closed design and they aren’t sure if the VOCs are accurate enough, so good choice there Atmotube.
Each time you launch the mobile app there is a communication between the device and your phone via Bluetooth and all the measurements are synced and saved into your phone, this process takes some time, like a minute or two and I wish it was bit faster. Although the product is quite polished, maybe in a future update they will manage to do this process faster.
In my opinion, Atmotube serves two proposes: First it helps you see the air pollutants (PMx & VOCs) and study them later and second it will help you and the people around you to get more conscious about air pollution as it will awaken people’s curiosity. It meets a lot of my must-have criteria for a portable AQM.
