Ultrasonics refers to signals that are above the human hearing span (>20 kHz), and usually in the 40- to 70-kHz range. These signals are used like radar—they’re radiated toward a target and reflected ...

The library gives control over up to 16 parallel working PIR devices over I2C. The idea for this library came up in a discussion about how to fully cover an area with PIR sensors without blind spots ...

In recent years, the demand for smart security and automated monitoring systems has increased significantly due to growing safety concerns and the need for real-time surveillance. Traditional security ...

Abstract: This paper presents a wireless communication system utilizing a 433MHz RF module alongside human presence detection using a Passive Infrared (PIR) sensor. The system is designed to enable ...

Abstract: LabVIEW is a graphical programming language, used in many research fields for designing communication algorithms and simulating traditional as well as real time signals. Arduino kit can be ...
