SEZO PM
Complex Environment Monitoring
SEZO PM is a compact sensor, measuring environmental parameters, air quality, temperature, humidity and air pressure. This handy device is suitable for outdoor environment monitoring in a wide range of environmental conditions, especially at low temperatures.
The new generation of SEZO products for air quality measurement is a guarantee of greater accuracy of measurements, as well as a greater temperature range of work with the highest, undisturbed precision. In SEZO PM, we installed the heat sensor outside, thanks to which we are able to achieve higher accuracy of both temperature and air humidity measurements. Thanks to the conditioning track that we used in the device it has highly precise PM measurement despite air humidity that can affect measurements.
MEASURING AIR QUALITY
SEZO PM provides information on air quality by measuring the levels of PM1, PM2.5 and PM10, which are very harmful to human health and life. The device thus provides information on whether it is safe to be outside.
LTE-M TECHNOLOGY
LTE-M is a low-power long-range network designed specifically for IoT devices for direct connection to 4G networks. It supports high-speed data transfer enabling real time communication – thus enabling monitoring of resources.
PLATFORM INTEGRATION
SEZO PM is integrated with the Orange Live Objects platform, which facilitates the preview and analysis of the data collected by the device through easy USB configuration or preconfiguration of the device according to customer requirements. It is also possible to connect the device to another, already existing platform that your company uses, thanks to the possibility of easily establishing a network server, such as The Things Stack, Chirpstack. The decoder is available for download on the SEZO Github repo.
When designing SEZO PM (derived from SEZO AM), we used the knowledge gained during the construction of its predecessor. Thanks to this, we were able to reduce the number of sensors in it – this allows us to focus on the basic parameters and achieve more precise measurements. It is possible even at high humidity (above 95%) and low temperature (up to -30 degrees Celsius).
- SEZO PM monitors environmental parameters such as temperature, air pollution (PM), humidity, atmospheric pressure.
- SEZO PM transmits data at the moment of an event or in user-defined intervals. The device is configured using OTA (over the air) method, i.e. wirelessly.
- SEZO PM can be used both indoors and outdoors – it operates without any interference at temperatures ranging from -30 to +60°C.
- The SEZO PM uses LTE-M technology and has a nanoSIM socket.
- The SEZO PM device is powered by an external power supply unit with a voltage of 230V, so it can be connected to a common electrical outlet.

Use Cases
SCHOOLS
SEZO PM makes schools a safer place for children and staff.
School management levarages SEZO PM to detect and prevent exposure to floating dust on school yards and parking lots and therefore make schools a safer place for both, children and staff.
SEZO PM measures particulate matter such as PM1, PM2.5, and PM10.
The device is powered via a AC 230V power supply, and can therefore be used conveniently in various locations with a standard power socket.
INDUSTRIAL PRODUCTION SITES
SEZO PM enhances security processes at industrial manufacturing sites.
Industrial producers have additional health and safety conditions in the workplace. Thanks to constant air measurements, SEZO PM allows you to reduce the risk of unconsciously worse working conditions and, in the long run, occupational diseases.
The device is capable of sending data to the Orange Live Objects platform via LTE-M and pulls data from the environment like dust levels (PM1, PM2.5, PM10) and temperature levels.
SEZO PM
a new form of our best devices
We listen to the needs of our clients
The new SEZO devices are proof that we listen to the needs of our customers – they inspired us to create the SEZO PM model as a device for precise measurements in very low temperatures, to be applied in a country where temperatures drop even below -30 degrees Celsius – precisely in those conditions our product prooves its worth.
It is thanks to the new design that SEZO devices can take measurements in places where there is high humidity and where the temperature drops significantly.
SEZO PM has an added feature: it allows customers to share the localization of the device (on demand). Thanks to that their current location, despite being connected to a fixed device, can be verified.
Where can SEZO PM be used?
- industrial sites
- Smart City projects
- winter resorts
- coastal zones
- places with high humidity, where air quality is important.
