This project is an Arduino-based water level sensor using an ultrasonic sensor to measure water height in a tank and display the results via LEDs and the Serial Monitor.

Using an Arduino Nano, ultrasonic sensor, and buzzer, it can sense objects in their way and provide an instant audible alert to them. So they can navigate independently. The best part of this blind ...

Just like smartphone cameras, these sensors have a finite resolution. The higher the resolution, the finer details the sensor can discern about your finger, increasing the level of security.

Okay, we’ve just left May and stepped into June, why are we talking about Arduino Day — traditionally a March 16 th event where makers congregate and share projects? I live in Ho Chi Minh City ...

Additionally, the mechanical nature of these sensors can lead to wear and tear over time, which may affect their accuracy and reliability. Ultrasonic level sensors are non-contact devices that use ...

(14 points) Class Activity: Wiring Instructions and Arduino Code Instructions for Running the Ultrasonic Sensor In this class activity, you will be guided through the process of wiring your ultrasonic ...

Join us as we wrap up the biggest tech show of the year, CES, revealing all the most interesting new gadgets and devices we’ll be enjoying over the year ahead. Our big focus this year has been ...

By the end of the guide, you’ll not only have a fully functional bidirectional counter but also gain hands-on experience with IR sensors,16x2 LCD display, Arduino programming, and some ...

Abstract: This paper proposes an intensity-modulated liquid level sensor based on cascaded long-period fiber grating (LPFG) and fiber Bragg grating (FBG) structure with temperature compensation. Its ...

In high-risk tank environments, liquid-level sensors must detect minor changes with a broad range. However, achieving high-precision liquid-level sensing is challenged by issues such as low resolution ...
