Abstract: Apparatuses, systems, and methods are described for providing a sensor device. The system includes a control unit and a sensing unit. The sensing unit is coupleable to the control unit via a current loop and includes an input terminal coupleable to the current loop, at least one energy storage unit configured to be charged to a first voltage from the input terminal, a sensing element configured to sense an environmental parameter, wherein the sensing element receives power from the at least one energy storage unit at a second voltage, and wherein the second voltage is lower than the first voltage, a controller configured to receive a sensor signal from the sensing element and to generate an output signal, and an output terminal coupleable to the current loop and configured to transmit output corresponding to the output signal to the control unit via the current loop.
