These days, most of us have a smartphone. They are so commonplace that we rarely stop to consider how amazing they truly are.

Chapter 1, page 11 This code is basic but allows the reader to gain insight into key elements for several other projects in this book. It combines two pieces of code that are listed in the examples ...

This is a library for the Arduino IDE that helps interface with ST's VL53L4CD time-of-flight distance sensor. The library makes it simple to configure the sensor and read range data from it via I²C.

Abstract: Reconfigurable intelligent surfaces (RIS) offer efficient control over the amplitude/phase of reflected/transmitted signals, providing a cost-effective solution for direction of arrival (DOA ...

I purchased one of each of these cheap sensors recently from aliexpress for testing purposes. Compared with the ubiquitous HC-SR04 (*), I liked the idea of having a combined emitter/receiver, i.e.

Abstract: Synchronous intensification of spatial resolution and sensing range has attracted widespread concern for distributed acoustic sensor. The pulse compression approach as a representative ...
