SKU: WM-I2 Category:

Utility meters, sensors can be connected to our pulse signal counter and transmitter modem.

The device collects the consumption values and sending the data through the NB-IoT cellular network to the data center of the energy provider.

The smart modem has a standalone and intermittent operation. It wakes up at the configured interval to transmit the collected data to a server IP address.

The modem has a special internal battery, which provides energy for more than 10 years (or 4 000 data sending cycles).

The device can be installed to smart meters (water, gas, heat, electricity), sensors or smart energy networks of the public utilities.
