Abstract
A system and method for a low cost fluid flow sensor is described. One embodiment includes a fluid flow sensor comprising a first resistance temperature detector configured for generating a flow signal, wherein the flow signal is based on a fluid velocity, and wherein the first resistance temperature detector is configured for a fluid temperature range; a second resistance temperature detector configured for generating a temperature signal, wherein the temperature signal is based on a fluid temperature; and a controller coupled to the first resistance temperature detector and the second resistance temperature detector, the controller configured for receiving the flow signal and the temperature signal, wherein the controller takes a first controller action when the temperature signal is within a temperature signal range substantially representative of the fluid temperature range, and the flow signal is within a flow signal range, wherein the flow signal range is determined based on the temperature signal.
