A small PlatformIO/Arduino project that measures distance using an ultrasonic sensor (HC-SR04 or similar) and prints the measured distance over the serial port. This README explains how to open the ...
Ultrasonics refers to signals that are above the human hearing span (>20 kHz), and usually in the 40- to 70-kHz range. These signals are used like radar—they’re radiated toward a target and reflected ...
The last two decades have seen substantial improvements in ultrasonic plastic-welding machines. Bench-top models feature proportional-valve controls, linear encoders, line-voltage regulation, internal ...
The sendEmail () function is responsible for triggering the email alert when an object is detected. A secure Wi-Fi client is ...
WE had observed 1 that the heat generated by ultrasonic waves in carbon disulphide and in other liquids, such as toluene and xylene, is not in conformity with their widely divergent absorption ...
Abstract: This article presents an ultrasonic gas meter based on a scandium-doped aluminum nitride (Sc0.2Al0.8N) piezoelectric micromachined ultrasonic transducer (PMUT) array, where the ...
Abstract: In the context of the ongoing digital revolution, the food industry grapples with significant challenges concerning quality control, safety, production efficiency, and economic viability.
