Abstract

A Micro Electro-Mechanical System (MEMS) device comprises an evaluator circuit that receives a temperature signal, where the evaluator circuit compares the received temperature signal to a lower threshold value and an upper threshold value, and where the evaluator circuit generates an evaluation signal indicating when the temperature signal is between the lower threshold value and the upper threshold value; and a loading circuit that receives the evaluation signal, where the loading circuit generates a first pre-set output signal indicating when the temperature signal is between the lower threshold value and the upper threshold value, and wherein the loading circuit generates a second pre-set output signal when the temperature signal is not between the lower threshold value and the upper threshold value, such that the MEMS device functions as a 2-wire electronic sense circuit providing both an indication state and deriving power from an external two-wire sense circuit.
