This project implements a 3D ultrasonic anemometer for measuring wind data across three axes: North-South (NS), East-West (EW), and Top-Bottom (TB). The system uses ultrasonic transducers and ...

#define DHTTYPE DHT21 // DHT 21 (AM2301) // Connect pin 1 (on the left) of the sensor to +5V // NOTE: If using a board with 3.3V logic like an Arduino Due connect pin 1 // to 3.3V instead of 5V! // ...

Abstract: This paper deal with the design and implementation of low cost, indigenous 2-axis ultrasonic anemometer having real time SD card and Internet of Things (IOT) enabled data logging. Ultrasonic ...

Abstract: In this paper, an ultrasonic anemometer based in the time of flight is presented. The wind speed and direction is obtained using four ultrasonic transducers in an orthogonal configuration.

Anemoment LLC, a specialized meteorological instrument design firm located in Longmont, CO, announced today the availability of the TriSonica™ line of “whisper-weight” 3-dimensional wind sensors: the ...
