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: Surface acoustic wave (SAW) pressure sensors are widely applied for their strong environmental adaptability, ease of wireless integration, and low cost. With the extension of atmospheric ...

Abstract: Achieving high sensitivity and structural integration in metamaterial sensors for liquid permittivity measurement remains a significant challenge, primarily due to limited electromagnetic ...

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 ...
