WM-i MAX

Robust, ultra low-power cellular IoT data logger, which comes with a built-in LTE Cat.M, NB-IoT cellular module ensuring reliable data transfer in any environment.

The device can be connected to two sensors due to its analog inputs (4..20mA or 0-10V).

Easily upgrade existing meters and sensors with cellular connectivity, safeguarding your investments without the need for costly replacements!

Offering a standalone operation, it performs reliable automated sensor or meter readings. The device allows connection of 2 analogue sensors through its inputs.

The WM-i MAX device receives and collects signals of connected two sensors, then it transfers all data at predetermined intervals to the Microsoft^® Azure IoT platform with MQTT protocol and TLS encryption through the LTE Cat.M / NB-IoT network.

The easily installable device was designed for long-term, maintenance-free operation, the WM-i 4..20mA boasts a high-capacity battery lasting up to 10 years and an IP68 waterproof casing, making it ideal for challenging environments.

Optionally, add-on extension possibilities are available to extend capabilities for PoCs, unique orders (e.g. different connections, adding sensors).
