This Instructable demonstrates a method of increasing the measuring range of the popular HC-SR04 ultrasonic distance sensor. The enhancement in range is based on reducing the 'field of view' (FOV) of the basic sensor by using it as a feed element for a parabolic dish. No changes have been made in the electronics of the basic HC-SR04 sensor.

May 2, 2024 · Learn how to use the ultrasonic sensor (HC-SR04) with Arduino. This tutorial will teach you what it is, how to assemble the sensor on Arduino, and, at the end, you'll implement it into an alarm system project.

Mar 7, 2023 · People very successfully use parabolic dishes of < 1 m diameter with microphones to record bird calls and human conversations at large distances. Extensive tests and review of the Wildtronics product line here: Review: Wildtronics Parabolic …

Aug 16, 2017 · With a single sound emitter, you can use a large focusing dish to give a (relatively) nondivergent beam, but the beam will be roughly the diameter of the dish.

Aug 5, 2017 · In this project I will introduce you to the HC-SR04 Ultrasonic sensor. It works by sending sound waves from the transmitter, which then bounce off of an object and then return to the receiver. You can determine how far away something is by the time it takes for the sound waves to get back to the sensor. Let's get right to it!

Aug 12, 2021 · Scroll down to read more about how to make a radar with ultrasonic sensor and Arduino. The programming is done in the Arduino IDE and the radar is displayed using the Processing IDE. In simple words this is how the project works. The ultrasonic sensor is mounted on a servo motor which rotates sideways.

Learn how to use ultrasonic sensor HC-SR04 with Arduino, how ultrasonic sensor works, how to connect ultrasonic sensor to Arduino, how to code for ultrasonic sensor, how to program Arduino step by step.

The HC-SR04 is a typical ultrasonic sensor which is used in many projects such as obstacle detector and electronic distance measurement tapes. In this Instructable I'll teach you how to interface the HC-SC04 with an Arduino Uno.

Apr 26, 2024 · In this article, we will study how to design this ultrasonic sensor using the Arduino board and programming software. We will study the specifications needed for this sensor, and the methods and circuit diagrams used for designing this sensor.

Mar 8, 2024 · 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 ultrasonic sensor, and then we'll add the I2C LCD display to the project at the end.
