This project demonstrates how to interface an HC-SR04 ultrasonic distance sensor with an SSD1306 OLED display using the STM32 Blue Pill microcontroller. The system measures distances and displays them ...

Abstract: This paper proposes miniaturized, lightweight and ultrasensitive planar metamaterial sensor for relative permittivity measurement of nondispersive materials. The proposed sensor is designed ...

Abstract: A hybrid interferometer sensor based on the enhanced Vernier effect was proposed for the simultaneous measurement of strain and temperature. The sensor was composed of a Fabry-Perot ...

A quantum net for dark matter: A distributed intercity network of quantum sensors is placing additional constraints on the parameters that axionic dark matter could have. (Courtesy: USTC) A new of way ...
