This letter describes a robust voice activity detector using an ultrasonic Doppler sonar device. An ultrasonic beam is incident on the talker's face. Facial movements result in Doppler frequency ...

The Ultrasonic Position Sensor industry key market players adopt various strategies such as product launch, product development, collaboration, partnership, and agreements to influence the market.

This Arduino code utilizes an ultrasonic sensor to measure distances. When an object is detected within a fix distance , the connected motors trigger a sequence: move backward, turn right, turn left, ...

In this paper, we present a single-chip 65 × 42 element ultrasonic pulse-echo fingerprint sensor with transmit (TX) beamforming based on piezoelectric micromachined ultrasonic transducers directly ...

A system that uses a PID controller to balance a ball on a tiltable platform. The system is built with an Arduino, ultrasonic sensor, and servo motor, with PID gain tuning via potentiometers. The ...
