With the rapid growth of IoT-based monitoring systems, staying informed about what’s happening in real time has become extremely important. Whether it’s detecting an intruder, monitoring equipment, or ...

As a result, remote control technologies are being widely adopted across various sectors. Among the many components used in ...

The analog value from the sensor is converted to distance using either a polynomial fit function up to fifth order or a power fit function. By default, this library is set to use polynomial ...

This project implements a cost-effective intruder detection system using an Arduino Nano and IR sensor. The system detects unauthorized motion within a 2-30 cm range and triggers immediate audible ...

Abstract: This paper reports on a surface acoustic wave-based infrared sensor with an aluminum nitride thin film deposited on interdigital transducers. The result of the coupling-of-modes (COM) ...

Abstract: We report the development and application of a compact and sensitive mid-infrared nitric oxide (NO) sensor using off-beam quartz-enhanced photoacoustic spectroscopy (QEPAS). This QEPAS ...
