The Korea Research Institute of Standards and Science (KRISS) has developed an ultrasonic sensor technology that applies a ...

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 Shelly Flood Gen4 is an affordable, highly versatile water leak detector with Matter support, multiple wireless options, ...

A team led by La Trobe University has drawn inspiration from nature to develop a breakthrough sensor that can rapidly track tiny molecular changes in blood, paving the way to real-time, personalized ...

Deep canyons in the Andes are the perfect location to catch the most energetic particles in the universe. Carlos ...

Abstract: This paper presents an integrated Bluetooth Low Energy (BLE) planar inverted-F antenna (PIFA) sensor designed for noncontact liquid level detection using microwave sensing in the 2.4 GHz ISM ...

This project is a simple automatic toll gate system built using Arduino, an ultrasonic sensor, a servo motor, and a 16x2 LCD display. The system detects when a vehicle approaches the gate, opens the ...

Engineers at the Korea Research Institute of Standards and Science (KRISS) have developed a new ultrasonic sensing technology that can detect structural defects in dangerous environments where ...

Abstract: Conventional phased-array ultrasound can detect defects in nuts; however, accurately reconstructing their irregular shapes and precise spatial structures remains challenging. To faithfully ...
