Tiny and autonomous IEEE1451 Sonic Anemometer to deploy in environmental Wireless Sensor Network

Abstract

Wind speed and direction are important parameters in the study of applied meteorology, for example, in weather prediction, air pollution, transport safety and structural safety. In this paper, we propose the design and deployment of an interoperable Smart Ultrasonic Anemometer that uses the IEEE 1451 standard and operates in a Wireless Sensor Network (WSN). This standard permits interoperability and introduces self-calibration and self-configuration tasks. We include power management considerations to calculate the energy consumption using a low power sampling protocol BMAC with variable duty cycle. Experimental tests are included to study the current consumption using an energy harvester with solar panel and super capacitors to increase the reliability and lifetime of the sensor node.
