Total mastery over the pinout and functionality of the PCA9306 for conversion of logic levels from 5V to 3.3V. A step-by-step interfacing diagram for the PCA9306 to Arduino UNO. Working example with ...

Abstract: Flood detection is problematic, especially in rural areas with limited or nonexistent monitoring infrastructure. Smaller streams and flood-prone areas frequently go unmonitored, leaving ...

This project pairs a pressure transducer with 2 microcontrollers which read and publish the water pressure periodically to an mqtt server. Why 2 microcontrollers? Because the pressure transducers I ...

Abstract: This article proposes a nondestructive multichannel sensor for liquid-level detection based on spoof surface plasmon polaritons (SSPPs). A mathematical model for liquid-level sensing is ...

An Arduino library for the Hi-Link HLK-LD2450 24Ghz FMCW radar sensor. This sensor is a Frequency Modulated Continuous Wave radar, which makes it good for presence detection and has some interesting ...

Differential pressure sensor is an electronic device designed to measure and calculate pressure difference between two points, one connected to each side of the sensor. Silicon-based board mounted ...
