Abstract
A sensor includes a sensor device mounted in a sensor housing which defines therein a gas conduit to permit a gas to flow therethrough in a predetermined flowing direction. The sensor device includes a sensor module having a sensor circuit board, a gas flow sensing chip and a plurality of first deflecting members. The gas flow sensing chip is disposed on a major surface of the sensor circuit board that faces the gas conduit so as to measure the flow rate of the gas flowing through the gas conduit. The first deflecting members are disposed on and protrude from the major surface, and are elongated in the flowing direction so as to rectify the gas flowing therealong. The rectified gas is subsequently guided to flow over the gas flow sensing chip for flow rate measurement.
