When [Electron Impressions] used a powerful ultrasonic array to project a narrow beam of sound toward a target, he described ...
Default value for maximum measurement distance is 4m, since HC-SR04 sensor can't measure reliably beyond that. However, if you are using another sensor or if you you don't care about distances larger ...
Arduino 20th anniversary projects at the University of Padua include a gesture-control car, solar IoT monitor, and BLE swim ...
Abstract: We propose a one-millimeter-scale linear ultrasonic motor and its feedback control system with a Hall sensor. The size of the stator measures 1.6 mm in height, 1.6 mm in width, and 0.3 mm in ...
Abstract: Proximity sensing is of great importance for robot control during human–robot collaboration (HRC). Commonly used machine vision sensors or photodetectors are subjected to the light block ...
This is a library for the laser particle sensor module PM2005 manufactured by Wuhan Cubic Optoelectronics. The PM2005 module counts airborne particles of different sizes in catagories of 0.3, 2.5, and ...
