Hardware For Ultrasonic Anemometer

Abstract

The article describes the development of hardware for a low cost ultrasonic anemometer. The core of the device is a STM32F103CBT6 processor, a part of the Maple Mini development platform. In addition to ultrasonic measurement circuits, meteorological sensors and communication circuits are also connected to the processor. The paper also discusses various methods to excite ultrasonic transducers and to process the received signal; the latter procedure embodies the basis of the designed instrument. All the electronic components are embedded in a self-heating plastic case. The sensor satisfies all relevant safety and weather resistance requirements.
