This document is aimed at the Arduino developers, radio experimenters, hobbyists and anyone interested in building a receiver based on the Si473X IC family from Silicon Labs. This project is about an ...

Although it dates back to the early days of the Marconi Company in the 1920s, the Franklin oscillator has remained a relatively obscure circuit, its memory mostly kept alive by ham radio operators who ...

I’ve just come across a no-name non-contact, high-precision 80 GHz mmWave radar sensor for liquid level detection with a 40m range, ±5mm accuracy, and Modbus communication over UART. The 0.15m to 40m ...

This project demonstrates an Arduino-powered wireless frequency meter that can measure the frequency of sinusoidal AC transmissions ranging from 50Hz to 3kHz. Figures 1 and 2 show prototype ...

These meters generally use a sensor to relay the flow measurements to a reading device. Nearly all types of flowmeters, from ultrasonic to turbines, are offered with pulse output flow signals. Sensing ...

SparkFun has launched a new Qwiic breakout board for the Acconeer XM125 60 GHz pulsed coherent radar sensor that can measure distance to humans even through walls and works at a distance of up to 20 ...

Abstract: This research aims to create a Smart Energy Meter that can monitor, notify, and terminate excessive electrical energy use on the Internet of Things (IoT) using the Blynk Iot application as ...

Abstract: This study presents an IoT-based ELF magnetic field meter that can measure magnetic flux density from 100nT. The proposed device has a flat response across the frequency range from 40Hz to ...

Neil Hannay explains how to understand flow meter sensor and pulse output types for efficient system operation FLOW meters have developed into many forms over the years, from mechanical devices – such ...
