Full Review
Atmotube PRO is a small, portable air quality monitor ideal for people who travel frequently, especially to places with extremely polluted and unsafe air.
It connects to a smart app via Bluetooth and provides real-time air quality data.
While it’s an impressive compact device with accurate sensors, I find it less practical for everyday use, particularly at home, in the office, or as a tabletop air quality monitor.
This is mainly because it lacks a display, making air quality readings less convenient compared to devices designed specifically for desk use.
Sensor Types & Accuracy
The Atmotube PRO uses three different sensors to detect current air quality.
The first and most important one is the Sensirion SPS30 laser particle sensor, which detects airborne particles in real time in a range of 0 to 1.000 µg/m³, with an accuracy of ±10 µg/m³ or ±10%. This places it among the most precise sensors currently available on the market. This is the same accuracy as of the Qingping Gen 2 air quality monitor.
For measuring VOC levels, it uses the Sensirion SGPC3, which measures VOC concentrations in a range of 0 to 60 ppm with an impressively high accuracy of ±15% of the measured value.
Finally, the Bosch BME280 sensor is responsible for measuring temperature, humidity, and air pressure. This sensor is also very accurate, and in my opinion, a better or more precise sensor is not necessary for this type of device.
| Pollutant / Parameter | Sensor Model | Measurement Range | Typical Accuracy |
|---|---|---|---|
| PM1 & PM2.5 | Sensirion SPS30 | 1−1.000μg/m3 | ±10μg/m3 (0−100μg/m3)±10% (100−1,000μg/m3) |
| PM10 | Sensirion SPS30 | 1−1.000μg/m3 | ±25μg/m3 (0−100μg/m3)±25% (100−1,000μg/m3) |
| TVOC | Sensirion SGPC3 | −40 to +85∘C | ±15% of measured value |
| Temperature | Bosch BME280 | −40 to +85∘C | ±1∘C (Range 0−65∘C) |
| Rel. Humidity | Bosch BME280 | 0−100% RH | ±3% RH |
| Atm. Pressure | Bosch BME280 | 300−1,100 hPa | ±1 hPa |
Overall, I would say that the Atmotube PRO uses high-quality and accurate sensors with very small deviations and fluctuations.
The Sensirion SPS30 is designed to last up to eight years while providing accurate and reliable data, although in practice, it often lasts much longer.
The only drawback of this sensor is that it is less precise when measuring PM10 particles, where it can show deviations of up to ±25 µg/m³ or ±25%.
For most users who plan to use this monitor, I believe the main focus will be on PM2.5 particles and VOC levels, which are measured with high reliability and accuracy.
Measured Data Reporting
The primary way to view and interpret data collected from the sensors is through the smart app.
This means you must connect the Atmotube PRO to the app; otherwise, you lose access to all features and the device’s main purpose, which is to view current air quality and adjust the settings.
One particularly interesting feature is that the Atmotube PRO tracks your location via GPS, but only when it is connected to a smartphone.
In this way, Atmotube provides real-time air quality data for the locations you move through. This is especially useful if you want precise air quality information for the exact places you visit, rather than relying solely on data from fixed monitoring stations in the area.
The app displays data for PM1, PM2.5, PM10, TVOC, temperature, humidity, and air pressure.
LED Indicator
The Atmotube PRO features an LED indicator on the front of the device, positioned just above the button, which changes color based on the current air quality.
This is essentially the only way to check air quality directly on the device itself.
The LED indicator lights up in different colors depending on air quality or some other allerts and notifications related to the device, and you can refer to the table below for a detailed explanation of what each color represents. When you press the button once, the LED lights up in a color representing the current Air Quality Score.
| LED Color / Pattern | Meaning |
|---|---|
| Blue/Green/Yellow/Orange/Red (solid on button press) | Air Quality Score indication |
| Blinking Orange | VOC sensor heating/pre-heat |
| Solid Orange | Charging |
| Solid Green | Fully charged |
| Blinking Red (fast) | Firmware update mode |
| Blinking Red (slow) | Low battery |
| Blinking White | Hardware error |
Frankly, the LED indicator is not very clear, and at times, the yellow and orange colors look very similar. Because of this, without using the app, it is quite difficult to get a serious and accurate understanding of the current air quality.
Atmotube App
The Atmotube PRO comes with a smart app that works on both Android and iOS devices.
The device connects to the app via Bluetooth, which means your phone needs to be near the device whenever you want to read air quality data.
Among all the features, the ones I like the most are the highly accessible and easy-to-read user interface, rich and well-organized data, historical air quality information, and advanced settings.
In addition to this, you can access air quality data through Atmotube’s cloud API and export all recorded data as a CSV file. Keep in mind that the device stores data locally for about 10 days.
Through the app, you can also view a live map that displays local air quality data collected by your own sensor, as well as global air quality data from other users.
Another important point is that the Atmotube PRO uses GPS data from your phone, allowing it to always display the exact location.
Cleaning & Calibrating
When it comes to calibration, the Atmotube PRO uses a pre-calibrated PM sensor that doesn’t require user calibration, as it is factory calibrated.
An important aspect of this sensor is that it has not shown significant deviations over its expected lifespan of up to eight years.
For the VOC sensor, there are two calibration methods: automatic and manual. With automatic calibration, the sensor learns what the cleanest air in your environment is and sets that value as zero. This process takes between 12 and 24 hours after the device is first powered on.
In addition, manual calibration can be performed through the smart app.
If you feel that the VOC readings are not fully accurate, you can reset the sensor at any time by selecting “Reset VOC Calibration” in the settings. After the reset, the sensor will begin the automatic calibration process again.
Besides these measurements, Atmotube also allows you to manually adjust offsets for temperature, humidity, and air pressure, which functions as the calibration method for these parameters.
Overall, the Atmotube PRO doesn’t require any special maintenance or calibration, except in cases where you notice the VOC sensor is not performing optimally.
You may occasionally remove dust from the air intake openings, but this should be done gently and without blowing forcefully into the openings to avoid damaging the sensors.
Design & Build Quality
The Atmotube PRO is a high-quality air quality monitor built from a combination of polycarbonate and aluminum.
It is designed for long-term use and outdoor conditions, including exposure to rain, snow, and sunlight.
The device is primarily available in black with silver accents. There is also a white version, although it is not as widely available as the black model.
On the device itself, you will only find a single control button, an LED indicator, and the charging port.
Overall, I would say that the Atmotube PRO is a well-built device that should last for many years without any issues.
Airflow
The Atmotube PRO draws air in through the side of the device, with air exiting from the front.
It uses a small internal fan to pull air through the sensors, which helps ensure current and accurate air quality readings at all times.
To avoid potential damage to the motor, don’t block the airflow or place the Atmotube inside a backpack while it is running.
If you want to save battery life, you can adjust the measurement interval to read air quality data every 5, 10, or 15 minutes.
What comes with the device?
When you buy the Atmotube PRO, you get the pre-calibrated device along with a USB-C cable.
FAQ on Atmotube Pro
Does the Atmotube PRO require an app to work?
Yes, it does. I strongly recommend connecting it to the app, as this unlocks all the features the device offers. Without connecting it to the app, you will not be able to read air quality data or adjust any device settings.
Is there a way to view air quality data without using the smart app?
Unfortunately, there is no reliable way to view detailed air quality data without the app. The only on-device option is the LED indicator on the front, but this is not an effective solution for obtaining precise or accurate readings.
What is the battery life?
The Atmotube PRO uses a 2000 mAh battery that can last anywhere from 24 hours to up to 10 days, depending on the selected measurement interval.
If the device is set to continuously measure air quality, the internal fan runs constantly, and the battery drains in about 24 hours, or even faster in some cases. However, if you set the device to measure air quality every 15 minutes, the battery can last up to 10 days.
Hi, all very ,nice, i do have the PRO and the PRO 2 version and I can tell you that i am disappointed in the pro 2 version, especially for the CO2 measurements which is not measured by NDIR , and there is the flaw. the readings are absolutely incorrect, you need constantly adjustments, I even don’t understand why they produced such a device with no NDIR, I was happy with the Pro version and I thought it would be worth to buy the version PRO 2, but don’t, as It has no NDIR measurement capability. by the way on the forum several users don’t have any PM readings just as myself and the device is not ready due software/hardware issues
I can’t understand that either. Having an NDIR sensor is a must, especially for a trusted device from a brand like Atmotube. I bought and used the Pro version for some time, and it was a nice and useful gadget to have. However, after reading your comment, I can’t wait to buy and test the Pro 2 version, especially since I expected it to be a significant upgrade over the original Pro.
Thanks for sharing your feedback!
