TWSN-Hall is a radio device, battery powered, that performs the measure of DC current with Hall effect sensor.
A significant feature is the high resistance to mechanical shocks.

TWSN- Hall transmits measures at regular intervals to a TWSN family gateway. It is possible for the operator to program the alarm threshold in order to detect any possible overcoming of minimum or maximum levels of measured currents.
