SEZO Sp. z o.o. is an innovative Polish manufacturer of advanced IoT (Internet of Things) devices and wireless telemetry systems. The company was established as a technology spin-off of the renowned design firm WiRan Sp. z o.o., which has been supplying specialized radio-frequency (RF) electronics to the most demanding industries—including the space, military, and railway sectors—for over two decades.
The company’s name is derived from the phrase “Sensor Zone” which precisely defines its area of specialization. By harnessing the potential of modern, long-range, low-power wireless communication technologies (LPWAN), such as LoRaWAN, LTE-M, and NB-IoT, SEZO engineers have developed a proprietary line of smart sensors.
The brand’s solutions enable precise, maintenance-free, long-term monitoring of natural environmental parameters, including air quality, temperature, and humidity, as well as working and storage environments and industrial processes. The company’s portfolio also includes advanced asset tracking, critical infrastructure protection, and the design of customized IoT systems tailored to business requirements.
