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 ...
Soil salinity is a critical concern in agriculture when excessive soluble salts restrict a plant's water uptake, according to ...
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 ...
The RPS-429AA-80P-IS2 is a new intrinsically safe ultrasonic sensor can achieve precise distance measurement and object ...
In many applications, harsh ambient conditions present a significant challenge for sensor technology. In such cases, ultrasonic sensors that are largely unaffected by physical influences become ...
Abstract: Conventional phased-array ultrasound can detect defects in nuts; however, accurately reconstructing their irregular shapes and precise spatial structures remains challenging. To faithfully ...
