Air Quality Station
The new Air Quality Station allows the monitorization of the AQI to control pollution at cities and industries.
- Gases, particle matter, noise level and weather station
- Dual radio: LTE (4G) and LoRaWAN
- Machine learning algorithms applied
The new Air Quality Station allows:
- Measurement of the main air quality parameters: PM, CO, NO2, NO, O3, SO2
- Maximum accuracy thanks to cutting-edge hardware and machine learning algorithm
- Removable sensor cartridge for quick sensor exchange
- Communication via 4G and LoRaWAN
- Compatible with our high-quality weather stations
- Rich remote management thanks to the advanced cloud that facilitates OTA (over the air) programming and reconfiguration
- Real-time data visualization via the Cloud
- Multiple cloud compatibility: send data to any of the Libelium Bridge compatible clouds
- Robust, handy, and user-friendly
- Easy installation without batteries: simply connected to 220 V
- Back-up battery to keep configuration in case of power outage
- Very attractive price/accuracy ratio to facilitate capillary measurements in city centers with only one station in peripheral locations.
- Useful options: premium weather station, sound level meter (Noise Level Sensor Class 2) and particle matter.

Elements and Models
1. Air Quality Station Core
The core of the device includes:
- Main PCB with atmospheric pressure sensor and communication modules
- External sensors sockets
- External LED for pattern visualization
- Nano-SIM + Micro-USB socket
Air Quality Station SHT35 probe
The external SHT35 probe measures the air temperature and humidity.
This external SHT35 sensor probe is mandatory as the values provided by the sensor are used in the algorithms that finally calculate the gas concentration within the Libelium SCM.
2. Air Quality Station Sensor Cartridge
The gas sensors cartridge is composed of the PCB where the sensors are plugged and the outdoor protection enclosure.
Gas sensors included:
- CO (Carbon monoxide)
- O3 (Ozone)
- SO2 (Sulfur dioxide)
- NO (Nitric oxide)
- NO2 (Nitrogen dioxide)
A 2200 mAh backup battery is attached to the cartridge in order to keep the power supply of the gas sensors in case of sudden electricity blackout.
3. Optional complements:
3.1 Noise Level Sensor Class 2
The Noise Level Sensor Class 2 is extremely accurate and reliable: it meets the IEC-61672 standard, class 2. It is available in 2 versions: Indoors and Outdoors.
The Outdoors version comes with a weatherproof microphone (IEC-61672, class 1), prepared for real-world weather conditions (rain, wind, etc.). It also provides a 2-meter extension cable needed for a proper installation.
3.2 Weather stations
The device offers the possibility of connecting the MaxiMet weather stations GMX-240, GMX-550 and GMX-551 by Gill Instruments.
All of them measure parameters like wind speed, wind direction, precipitation, solar radiation, dew point, air temperature, air humidity or atmospheric air pressure.
3.3 Particulate Matter
The Particulate matter sensor detects small solid or liquid particles floating in the air. The origin of these particles can be the industrial activity, exhaust fumes from diesel motors, building heating, pollen, etc.
Particle matter device identifies:
- PM1: Mass (in μg) of all particles smaller than 1 μm, in 1 m³.
- PM2.5: Mass (in μg) of all particles smaller than 2.5 μm, in 1 m³.
- PM10: Mass (in μg) of all particles smaller than 10 μm, in 1 m³.
4. Network communication architecture
The Air Quality Station supports dual radio: LTE and LoRaWAN. Thus, there are two communication modes: “LTE” or “LoRaWAN with LTE backup”.
The Libelium Services Cloud Manager (SCM) allows the user to execute remote Over The Air programming (OTA), parameter configuration and reboot via LTE network.
Data is received in the Libelium SCM (Services Cloud Manager) where machine learning algorithms are applied to raw data in order to achieve gas concentration level in ug/m3 and ppb units.
5. Libelium Cloud Air Quality Station Service
Configure your nodes and receive the data by using the Libelium Air Quality Station Service on the cloud.
The Air Quality Station Service is framed on the Libelium Cloud (officially called Services Cloud Manager – SCM). The SCM allows the device management and allows the user to access other services hosted such as the Programming Cloud Service or the Bridge.
The Air Quality Station Service includes the Remote Configuration Form to manage the configuration values of the Air Quality Station node, that deals with the LoRaWAN network server requests, sending back a response if needed. The data sent from the Air Quality Station node will be sent to any compatible final IoT cloud service (Amazon, Azure, etc) using the Libelium Bridge (you will need a license to use the Bridge).
Through the cloud, the data sent from the Air Quality Station is collected to process and store the information. Users will be able to export the data through the Libleium Bridge using the connectors developed.
- Remote configuration: The device is configurable once installed at your location remotely, without the need to travel to the site to update the values.
- OTA: Firmware updates remotely without having to remove the node to update it.
- Reboot: Possibility to reboot the node remotely.
Innovate new solutions for the Internet of Things Market
Libelium participates in a project co-financed by the Spanish Ministry of the economy that promotes research to innovate new solutions for the Internet of Things Market.
The project “New device for high-precision monitoring and multivariate analysis of environmental factors’ has been co-financed by the Ministry of Economy and Business. This project is in the field of Digital Enabling Technologies (THD – 1/2019), within the State Plan for Scientific and Technical Research. File Number TSI-100110-2019-24
