To provide a fluid flow rate sensor which can more accurately and quickly determine a fluid flow rate and is self-calibrated and temperature compensated.
The fluid flow rate sensor includes a detection circuit which generates a first signal corresponding to an output voltage of a bridge circuit, and a second signal corresponding to a fluid temperature. A control module can more accurately and quickly determine the fluid flow rate based on the first signal, the second signal, and a look-up table. The look-up table includes a plurality of curves plotted according to data, indicating relationship among the fluid temperature, the output voltage, and the fluid flow rate. The fluid flow rate sensor is inherently temperature compensated and has a shorter response time.
