The ultrasonic distance sensor (HC-SR04) is a widely used electronic component for non-contact distance measurement. It operates on the principle of echo-ranging, where it emits an ultrasonic pulse ...

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 ...

This project measures the distance of an object using an HC-SR04 Ultrasonic Sensor and displays the result on a 16x2 I2C LCD. 📷 Demo (What It Does) Sends ultrasonic pulses from the sensor. Calculates ...

This system demonstrates water level and temperature monitoring on a 10.92cm (4.3-inch) TFT LCD using graphics and colour-changing animation of water filling a tank, along with a rising temperature ...

Abstract: In this paper, the results of developing an integrated information system for indoor parking are described. It consists of ultrasonic sensor modules for car-presence detection, tha data base ...

Proximity sensors that use ultrasonic sound waves calculate distance to an object using the time it takes to receive the echo from an ultrasonic burst. But, similar bursts from other sensors in close ...
