What’s the radar enthusiast to do? While it’s not radar, subbing in ultrasonic sensors is how [Dzl] built this sonar imaging system using a lot of radar principles. Initial experiments ...

Instead, a sensor that can detect mechanical stress is used to calculate the intensity of the returning ultrasonic pulse at different points on the scanner. Scanning for longer periods of time ...

For [Jianjia Ma]’s QingStation, he decided to build another type of wind sensor: An ultrasonic anemometer. Ultrasonic anemometers have no moving parts but come at the cost of significantly more ...

The ultrasonic technology enables 4-in-1 combined sensor operation. The instrument is suitable in binary gases for medical ventilators, assisting in the global pandemic that has resulted from the ...
