The authors propose a radar made with the ultrasonic sensor type HC - SR04, developed for Arduino. The novelty added by this paper is the development of specific libraries aiming to interface the ...

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 ...

The SGP30 is a digital multi-pixel gas sensor designed foreasy integration into air purifier, demand-controlledventilation, and IoT applications. Sensirion’s CMOSens®technology offers a complete ...
