Learn how to repurpose your spare ESP32 boards into cost-effective presence detection sensors using the Tommy Sense ...

A clock is by its very nature a device for measuring time, and thus it moves forward at a constant rate. But how about in a ...

Abstract: The research integrates IoT technology into a minimized wireless EV charging system and small wireless charging system in the framework of electric vehicles (evs) coupled with IoT-integrated ...

It can seem like Ignition web-based, HMI/SCADA software is everywhere, but the latest proof was the record-breaking attendance of 1,529 visitors at Inductive Automation’s 13th annual Inductive ...

Electrical energy is no longer treated as an unlimited utility. Every watt consumed has a cost impact, an efficiency implication, and in many cases a safety consequence. A smart grid in IoT is not a ...

This paper presents a methodology for the measurement of strain by means of strain-gauges, where the data acquisition is done by using an Arduino Uno board, due to the low-cost and the easy ...

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 ...

The ADT7470 Fan Monitoring library offers an I2C device that can monitor and control up to four fans. Further this module can daisy chain up to 10 (specific TMP05/06) temperature sensors. Please read ...

The September/October 2025 issue of Elektor Mag is out. The magazine explores a range of topics including short-range audio links, satellite tracking, wireless protocols, an inductive AM transmitter, ...

Abstract: The goal of this research is to increase road safety by measuring wheel RPM and identifying instances of over speeding using an inductive proximity sensor. An SMS warning is sent to a ...

The difference between high-side and low-side power switching is not apparent to many new designers but is a critical aspect of a viable circuit. Part 1 looked at the topology of high-side versus ...
