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 ...

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 ...

Our kit includes the Maker Uno RP2040 itself, four Grove to jumper cables, a USB-A to USB-C cable, a soil moisture sensor with one Grove cable, an HC-SR04 ultrasonic sensor with a Grove cable, a SG90 ...

Electronic system. The system used in the experiment was designed for using HC-SR04 ultrasonic sensor manufactured by OSEPP Electronics, installed in each Parshall flume, and an HC-SR04 ultrasonic ...

HC-SR04 Ultrasonic Sensor Overview . Before we go and understand how the ultrasonic distance sensor works, we will first learn what ultrasound is: ultrasound sound is a high-pitched wave, in which the ...

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 ...

Default value for maximum measurement distance is 4m, since HC-SR04 sensor can't measure reliably beyond that. However, if you are using another sensor or if you you don't care about distances larger ...

The sensor can be used for distance measurement, obstacle avoidance, etc. The measurement range is between 10.0 cm and 80.0 cm. Compared with the HC-SR04 module, its distance measurement range is ...
