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: This article presents the development of a microwave sensor designed to measure the permittivity of liquids using a novel slow-wave transmission line (SWTL) integrated with a composite right ...
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 ...
