Since the main chip core adopts single-chip microcomputer, the accuracy of measuring wind speed exceeds that of mechanical wind meter and other similar products. The anemometer uses high-brightness digital tube display to directly display the measured wind speed value M/S, exempting the stopwatch during use. Timing, calculate the average wind speed, check the measurement wind speed and the actual wind speed curve and other troubles, and store the measured wind speed in turn (total access 60 times), exempt from the record in the measurement due to the use of high-brightness digital display The wind speed value read in the dark in the well is clear and bright. The anemometer adopts a membrane type tact switch, which has good sealing performance, accurate and reliable, and is suitable for the application of a harsh environment in the underground.
