There is provided a thermal-type airflow meter that reduces the number of output signals of the sensor circuit and that can suppress the accuracy of flow rate detection from being deteriorated because due to a nonlinear sensor output characteristic and a response delay in the output signal, the output signal shifts toward the positive side or the negative side. A thermal-type airflow meter outputs one or both of a positive-side comparison signal that is at the positive side of a comparison threshold value and a negative-side comparison signal that is at the negative side of the comparison threshold value, outputs a coefficient multiplication signal obtained by multiplying an average signal acquired by averaging the comparison signal by an adjustment coefficient, and outputs, as a flow rate signal, a value obtained by applying the coefficient multiplication signal to increase correction or decrease correction of the amplitude increase signal.

A method and a system for transmitting a sensor signal, transmits the sensor signal in such a way that the analog electrical sensor signal is converted with the aid of a system for signal conversion into a converted signal and that this converted signal is transmitted to a control unit. As a result, the sensor signal is able to be transmitted to the control unit in a reliable manner and be evaluated thereby.
