This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...

In this tutorial, we'll guide you through interfacing an Arduino with an ultrasonic sensor to measure distance and show it on the Serial monitor. We'll start by explaining how to interface the ...

This project uses an ultrasonic distance sensor (e.g., HC-SR04) to measure the distance of objects and control two relays based on the measured distance. The system is simple, efficient, and can be ...

The Arduino Uno R3 Compatible Board is a microcontroller board that is based on the ATmega328. Arduino Uno has 14 digital input or output pins(where 6 can be used as ...

Arduino UNO: As you know that Arduino is a microcontroller-based open source electronic prototyping board that can be programmed with an easy-to-use Arduino IDE. The UNO is one of the most popular ...

This Ultrasonic Sensor Circuit consists of a set of ultrasonic receiver and transmitter which operate at the same frequency. When something moves in the area covered the circuit’s fine balance is ...

This is a small compact ultrasonic sensor for industry 4.0 features low power, real-time data communication for industrial robots. A fully assembled board has been developed for testing and ...

Ranging based on the reflection principle of ultrasonic wave propagating in the air has been widely used in modern life, such as car reversing radar, robot automatic obstacle avoidance etc. Aiming at ...

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 ...

This paper presents a 591×438-DPI ultrasonic fingerprint sensor. The sensor is based on a piezoelectric micromachined ultrasonic transducer (PMUT) array that is bonded at wafer-level to complementary ...
