The paper describes a way of measuring the wind speed and direction based on Time of
Flight. The system uses ultrasonic sound to detect the velocity of the wind. Time of Flight …

This paper presents the methodology for estimating the temperature in moist air, known as
dry-bulb temperature, using Piezoelectric over Silicon-On-Nothing (PSON) ScAlN pMUTs …

Structural Health Monitoring (SHM) gives a diagnosis of a structure assessing the structural
integrity and predicting the residual life through appropriate data processing and …

The measurement of wind speed may be performed using ultrasonic transducers based on
the principle of measuring the time-of-flight. However, due to the propagation of the …

Abstract The ultrasonic Time-of-Flight (ToF) estimation may be achieved using different
algorithms, such as signal processing techniques, artificial intelligence and, statistical …

This paper introduces a low cost receiver for wind velocity measurement using FPGA with
multiple ultrasonic transceivers. Wind speed is derived from the time taken by ultrasonic …
