In this paper, we present a prototype of a miniature radar system using the ESP32 microcontroller and an HC-SR04 ultrasonic sensor. The prototype utilizes a servo motor to rotate the ultrasonic sensor ...

Arduino/ESP8266/ESP32 library for HC-SR04 ultrasonic distance sensor. This library is used for measuring distance with the HC-SR04, which is an ultrasonic sensor that measures distances from 2 to ...

Producing items onto a screen simply by touching the air is a marvelous thing. One way to accomplish this involves four HC-SR04 ultrasonic sensor units that transmit data through an Arduino into a ...

This Repository contains the Arduino IDE Code for Interfacing Ultrasonic Sensor HC-SR04 with Arduino. This project is a part of physicsandelectronics.com. Detailed Explanation of Project with diagrams ...

They don’t sell the kit we’ve received directly, but you’ll find the Maker soil moisture sensor, HC-SR04 ultrasonic sensor, SG90 micro Servo, and 0.96-inch I2C OLED display on the company’s online ...

The HC-SR04 sensor sends an ultrasonic wave when triggered, being able to signal when the sent pulse is received. The Raspberry records the time between sending and receiving and the system calculates ...

In this project, we are going to interface an HC-SR04 Ultrasonic Distance Sensor module with ESP32 and we are going to know every little detail about the HC-SR04 Ultrasonic Sensor module, which is a ...

The dispenser uses ultrasonic sensor HC-SR04 to detect hands when these are put beneath the container. It dispenses the required amount of sanitiser automatically for specific time and then gets ready ...
