SEZO WM
Water Leak Monitoring
SEZO WM is an innovative, compact telemetry device that effectively detects water leaks and condensation. Thanks to the use of modern LTE-M wireless communication technology and integration with the Orange™ Live Objects platform, SEZO WM provides reliable real-time monitoring.
Key Features of SEZO WM:
- Multi-zone monitoring: The device is equipped with eight sensor strips, which allow for simultaneous monitoring of possible leaks in up to eight different zones. This is an ideal solution for large facilities, where precise location of problems is crucial.
- Intelligent reporting: SEZO WM sends data at set time intervals or immediately in the event of detection of flooding or attempted tamper. Reporting intervals are easily configurable via the Orange™ Live Objects platform, allowing the device to be adapted to the individual needs of the user.
- Tamper protection: Thanks to the built-in accelerometer, SEZO WM can detect unauthorized manipulation, such as dismantling. In the event of an alarm, the device automatically sends its GPS location to the online platform, which increases the security of monitored areas.

BATTERY POWER
SEZO WM is battery powered – 2x6000mAh (Lithium battery; Size C; 3.6V; 6000mAh; ER26500M). This allows installation regardless of the availability of 230VAC or stationary 48VDC power supply.
LTE-M TECHNOLOGY
LTE-M is a low-power, long-range network designed specifically for IoT devices to connect directly to the 4G network. It supports high data transfer rates, enabling real-time communication – which is conducive to monitoring resources.
PLATFORM INTEGRATION
SEZO WM is integrated with the Orange™ Live Objects platform, facilitating the viewing and analysis of data collected by the device. Configuration can be performed remotely configuring the device on the platform according to customer requirements. Additionally it is also possible to connect SEZO WM to other existing platforms, which is possible thanks to the ability to easily set the network server setting. The decoder is available for download on SEZO’s GitHub platform.
MAIN ADVANTAGES OF SEZO WM
- Reliable monitoring of water presence allowing for immediate notification of detected events.
- Detection of attempted tamper (dismantling and theft) of the device.
- Battery solution, enabling installation regardless of the availability of 230VAC or 48VDC power supply.
- Easy installation.
- Ready to operate in a few minutes thanks to easy online configuration.
- Reliable Orange™ LTE-M communication.
- Compatibility with the Orange™ Live Objects platform. Possibility of remote software update (FUOTA).
- SEZO WM supports 8 lines simultaneously, thanks to which it can separately monitor 8 different zones.
- Device adapted to work in indoor and outdoor conditions.

WHY CHOOSE SEZO WM?

- Easy installation: The compact design and battery power supply make the device quick and easy to install. It can be mounted anywhere, even in hard-to-reach locations.

- Versatile use: SEZO WM will work well in both commercial facilities, such as offices or warehouses, and public buildings. Its flexibility makes it a product suitable for various industries and needs.
Invest in SEZO WM and ensure peace and security with advanced leak monitoring. It’s not just technology – it’s your support in risk management and property protection!
Application Examples
WAREHOUSES FACILITIES

The SEZO WM device is an innovative solution that effectively monitors any water leaks inside buildings, which is crucial for protecting warehouse infrastructure and materials sensitive to flooding.
Facility managers easily use the SEZO WM and its features thanks to the hassle-free installation process. Due to the fact that the device is compact and battery-powered, it is enough to install it (by gluing or screwing it) in the place where we want to monitor possible water leaks, mount the sensors and the device is ready to work.
SEZO WM is able to transmit data using LTE-M technology.
OFFICE BUILDINGS

SEZO WM, with its ability to detect water leaks, is used by building maintenance personnel to ensure comfortable and stable working conditions for employees.
This compact, battery-powered device informs about any water leaks or condensation on the premises. Water leaks can be a threat not only to the building structure, but also to human health. Long-term exposure to mould can lead to Sick Building Syndrome (SBS), exposing people to various diseases (e.g. respiratory) caused by the building in which they work.
SEZO WM has a built-in LED diode that allows communication with the user.
