Ultrasonic wave wind speed measurement apparatus with temperature compensation

The invention provides an ultrasonic wave wind speed measurement apparatus with temperature compensation. The apparatus structurally comprises an ultrasonic wave speed measurement apparatus (1), an ultrasonic wave emitting end (2), an ultrasonic wave receiving end (3), a wind speed display (4), a wind speed LED dial (5). A sound wave wind speed measurement apparatus system is composed of a processor MCU (6), an ultrasonic wave generator (7), an ultrasonic wave receiver (8), a Bluetooth BLE (9), a temperature sensor (10) and a power supply management circuit (11). According to the invention, a wind speed is measured by reference to the speed of sound waves in air at different temperatures through a Doppler effect of the sound waves in flowing air according to a phase difference brought by the Doppler effect. The ultrasonic wave wind speed measurement apparatus with the temperature compensation can have the advantages of low cost, low loss, high portability and the like. 本发明提供一种带温度补偿的超声波测风速装置，其结构包括超声波测速装置（1）、超声
