We tested popular wideband O₂ controllers against lab-grade equipment to see how accurate their lambda readings really are under real engine conditions.

Abstract: This study proposes a radar-based heartbeat measurement method that uses the absolute value of the second derivative of the complex radar signal, rather than its phase, in combination with ...

Abstract: The article proposes a novel approach for in-orbit satellite antenna pattern measurement by means of a dedicated small measurement satellite (MES) that flies in Double-Cross-Helix formation.

This project utilizes an Arduino Uno CH340G development board paired with a DHT11 temperature and humidity sensor to create a compact yet capable environmental monitoring system. It measures ambient ...
