Anemometer for Drones: Compact Ultrasonic Model for Drone Use

Anemometer for drones, the ultrasonic anemometer is a high - precision meteorological monitoring device designed based on the principle of ultrasonic resonance. It is specifically developed for the low - altitude environmental monitoring needs of small drones and unmanned platforms. Its core technology emits ultrasonic pulses in different directions and measures the time difference or frequency difference of the sound waves during downwind and upwind propagation. Combined with the built - in algorithm, it can analyze wind speed and wind direction data in real - time. Compared with traditional mechanical anemometers, this device completely abandons vulnerable components such as wind cups and propellers and adopts an all - solid - state structure design, effectively solving problems such as mechanical wear, starting wind speed limitations (capable of measuring zero wind speed), and low - temperature icing, and improving long - term stability and environmental adaptability.

The instrument is equipped with a high - strength ABS engineering plastic housing with a diameter of only 46mm and a weight of 56g, combining compactness and durability. It is internally equipped with a low - power chipset, supporting a wide voltage supply of 5 - 30V, and the standby current is as low as 15mA (12V), significantly extending the endurance of the drone. In terms of core performance, the wind speed measurement range covers 0 - 60m/s with an accuracy of ±3%; the wind direction detection range is 0 - 359° with an accuracy of ±3° and a resolution of 1°, which can accurately capture instantaneous wind field changes.

The manufacturer provides two installation modes: top - mounted and bottom - inverted hoisting. Top - mounting can minimize the interference of the fuselage air flow and ensure data accuracy; bottom - mounting is suitable for scenarios with limited space or multi - sensor collaborative operations, expanding the compatibility of the drone platform. The data interface adopts the RS485 standard and supports the ModBus/ASCII protocol, facilitating seamless docking with the flight control system and real - time data transmission to the cloud or local monitoring platform.
