Sensirion inside Atmotube PRO 2 air quality tracker
Portable air quality tracker integrates multi-parameter sensing for real-time environmental monitoring
17 Jun 2026
Atmotube PRO 2 enables real-time monitoring of key air quality parameters via a portable device and companion app
Sensirion has announced that ATMO, a developer of portable and stationary air quality monitoring solutions, has integrated multiple Sensirion sensors into its new Atmotube PRO 2 portable air quality tracker. Designed for everyday use at home, at work, while traveling, and outdoors, Atmotube PRO 2 provides real-time monitoring of carbon dioxide (CO₂), particulate matter (PM), volatile organic compounds (VOCs), nitrogen oxides (NOx), temperature, and humidity, and now incorporates GPS to support autonomous air quality measurement mapping.
Advanced air quality monitoring in a compact, portable device
Atmotube PRO 2 is engineered to help users better understand the air they breathe throughout the day. The compact device offers up to 12 days of battery life and delivers continuous, real-time measurements of key air quality parameters. With integrated GPS, users can map pollution exposure and environmental conditions across different locations, supporting more informed decisions about where and how they spend their time.
Sensirion sensing solutions integrated into Atmotube PRO 2
The Atmotube PRO 2 portable air quality tracker incorporates several Sensirion sensing solutions to enable accurate, reliable, and energy-efficient environmental monitoring:
- STCC4 CO₂ sensor for accurate carbon dioxide monitoring with manual and automatic calibration
- SGP41 VOC and NOx sensor for advanced indoor air quality insights
- SPS30 particulate matter sensor for reliable PM1, PM2.5, and PM10 measurements
- SHT40 temperature and humidity sensor for precise environmental monitoring
These sensors are designed for high measurement accuracy and long-term stability while supporting compact integration and low power consumption, making them well suited to portable, real-time monitoring applications.
Long-term collaboration between Sensirion and ATMO
ATMO has used Sensirion sensors across several generations of its products. According to Alex Pyshkin, R&D Director at ATMO, “We have used Sensirion sensors in several generations of our products - we find them to be the optimal combination of accuracy, long term stability and small footprint, which makes it possible to integrate them into wearable / portable devices, just like our Atmotube PRO series”.

Frequently asked questions
How does Atmotube PRO 2 use Sensirion sensors to monitor indoor and outdoor air quality?
Atmotube PRO 2 integrates multiple Sensirion sensors to track key air quality parameters in real time. The STCC4 sensor measures CO₂, the SGP41 tracks VOCs and NOx, the SPS30 measures PM1, PM2.5, and PM10, and the SHT40 monitors temperature and humidity. Together, these sensors enable accurate, energy-efficient indoor and outdoor environmental monitoring in a compact, portable device.
What air quality parameters does Atmotube PRO 2 measure for personal exposure mapping?
Atmotube PRO 2 measures carbon dioxide (CO₂), particulate matter (PM1, PM2.5, PM10), volatile organic compounds (VOCs), nitrogen oxides (NOx), temperature, and humidity. With integrated GPS, it maps pollution exposure and environmental conditions across different locations, helping users understand how air quality varies at home, at work, while traveling, and outdoors throughout the day.
How does the Sensirion–ATMO collaboration enhance portable air quality monitoring?
The long-term collaboration between Sensirion and ATMO combines Sensirion’s accurate, stable, low-power sensors with ATMO’s portable Atmotube PRO 2 platform. This integration enables compact, wearable air quality trackers that visualize otherwise invisible pollution. By delivering continuous, real-time data on CO₂, PM, VOCs, NOx, temperature, and humidity, the partnership supports healthier decisions and greater awareness of air quality’s impact on wellbeing and performance.
