Hopkins researchers devised a method to measure antibody levels using glucometers, paving the way for accessible monitoring ...

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

As more households add solar panels, batteries and heat pumps, researchers at Purdue found that running them all on DC ...

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 ...

Learn how to make a simple device for monitoring the state of the ionosphere and the quality of shortwave signals using the CA3089 chip. Shortwave Propagation is the way radio waves in the 3 to 30 MHz ...

This research is aimed to explore the efficacy and comparison of low-cost light sensor measurements for agricultural applications. For this reason, TSL2561, BH1750, and TEMT6000, low-cost light ...

I'm trying to get block detection working on my HO scale model railroad. I found this page and liked the idea of using current transformers to detect the Digital Command Control signal inducing ...

Abstract: In this electric power era, energy efficiency and utilization are considered the primary motives in the electrical power sector. Due to the extensive use of AC power and different loads, ...

This repository contains the TrueRMS C++ library for Arduino. With this library it is possible to calculate the average value and the rms (root mean square) or effective value of the ADC input signal.

The difference between high-side and low-side power switching is not apparent to many new designers, but it is a critical aspect of a viable circuit. Applying power (voltage and current) to a load and ...

When working on simple DC systems, a small low-cost multimeter from the hardware store will get the job done well enough. Often they have the capability for measuring AC, but this is where cheap ...
