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

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 ...

The library gives control over up to 16 parallel working PIR devices over I2C. The idea for this library came up in a discussion about how to fully cover an area with PIR sensors without blind spots ...

This repository provides an edge-based method for detecting interfaces of an aqueous sample in a vial. It was initially developed for the autoHSP workflow to automate the result analysis through image ...

Scientists have developed a sunlight-driven method that uses liquid metals to extract clean hydrogen directly from both freshwater and seawater. By exploiting the unusual chemistry of gallium, the ...
