SEZO SL
Monitoring Valuable Objects
SEZO SL is a compact low-power telemetric device, measuring light intensity, equipped with an accelerometer, magnetometer and motion detector. It is used to monitor indoor conditions for various scenarios, including sub-zero temperatures and indoor air quality based on VOCs (Volatile Organic Compounds).
BATTERY POWERED
SEZO SL is battery powered. The use of low power LoRaWAN technology extends the battery life of the device up to 3 years of SEZO SL use. This allows the device to be mounted in any place, even in a hard to reach.
LORAWAN TECHNOLOGY
It allows the devices to use unlicensed ISM band – which means no subscription fees are required. The devices using LoRaWAN send data either after being triggered by an event (e.g. movement, switching on the light) or based on a fixed schedule (e.g. every 15 minutes).
PLATFORM INTEGRATION
It enables easy USB configuration or device preconfiguration 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, eg The Things Stack, Chirpstack. The decoder is available for download on github SEZO.
- SEZO SL measures such parameters as light level, temperature, humidity and air pressure.
- Built-in accelerometer and PIR sensors allow detection of human presence up to 3 meters from the device.
- SEZO SL transfers data at the time of the event or at user-defined intervals. Configuration is via USB.
- SEZO SL can be used indoors, also in situations where the temperature in the building is below zero – it works without interruptions at temperatures from -30 to +60°C.
- LoRaWAN technology enables long-distance data transmission – the distance between the device and the gateway can be up to 10 km.
- SEZO SL device is battery-powered and thanks to the use of LoRaWAN technology for long-distance transmission, the life of SEZO SL batteries is up to 3 years.

Use Cases
WAREHOUSES
The SEZO SL device enables controlling of the environment on the premises to ensure optimal conditions for storage. It is especially important in case of FMCG (Fast Moving Consumer Goods) such as packaged foods, toiletries or beverages, where the right temperature, as well as levels of humidity or luminosity need to be ensured.
Facility managers leverage SEZO SL as a part of the security system – the integrated accelerometer enables measurement of shocks and/or movements (e.g. of objects such as doors or stored goods) and can potentially decrease response time of facility security (more reliable than CCTV).
SEZO SL is capable of sending data via LoRaWAN to Orange Live Objects platform.
OFFICE BUILDINGS
SEZO SL, thanks to its ability to measure such environmental parameters as temperature and humidity, is leveraged by office managers to ensure not only comfortable, but also stable working conditions for the employees. Each parameter is configurable via USB and can therefore be adjusted to any specific needs.
SEZO SL also allows you to monitor indoor air quality in real time – by bringing your hand close to the device, the color of the LED will determine the current indoor air quality. In this way, the device ensures optimal conditions for office workers.
The device has an alarm threshold configuration for all measured parameters and is capable of sending data via LoRaWAN to Orange Live Objects platform.
GREENHOUSES
The SEZO SL device is used by greenhouse owners.
SEZO SL helps ensuring that a certain temperature, humidity and light level within the greenhouse is maintained. This, in turn, helps preserve a climate within the greenhouse optimal for the plants requiring such regulated conditions.
Thanks to the high sensitivity of the device and the accuracy of the measurements, the environment can be very precisely controlled.
The SEZO SL device sends data to the Orange Live Objects platform, which offers an easy and transparent way to monitor and analyse the data.
PUBLIC BUILDINGS
SEZO SL is used in public buildings such as railway stations, libraries and shopping malls to complement existing control and security systems.
A motion detector, which is an integral part of SEZO SL, allows to control the number of people staying inside buildings. This allows public institutions to estimate the number of people in a room and prevent overcrowding, thus avoiding the associated danger – for example in case of evacuation or panic.
In addition, SEZO SL is used by building managers as an alarm system – during building closure hours, SEZO SL monitors movement and reports any undesired activity.
