Just about every “getting started with microcontrollers” kit, Arduino or otherwise, includes an ultrasonic distance sensor ...

Abstract: Usually, four sensors are required to detect an object’s distance, shape, morphology, and permittivity. This work proposes a two-port microwave sensor array to comprehensively detect these ...

Abstract: This letter presents a novel method for distance variation robustness enhancement of microwave resonator-based sensor using artificial intelligence. Since any small change in the distance of ...
