IKEA has launched its new Gömpyssling LED light with sensor. It's a motion-activated light which automatically switches on when you open a cupboard or step into a space, then turns itself off after ...

Patients are being warned to stop using some glucose monitors made by Abbott Diabetes Care after the company found malfunctioning sensors may be linked to hundreds of adverse events and several deaths ...

Here’s a fun build from [RootSaid] that is suitable for people just getting started with microcontrollers and robotics — an Arduino-controlled two-wheeled robot. The video assumes you already have one ...

If you read about Hall effect sensors — the usual way to detect and measure magnetic fields these days — it sounds ...

A series where we find out which products the professionals (who really know what they’re talking about) actually use and really stand behind. Read more here. Maybe you’ve seen an influencer gliding ...

Many people believe that the LED was discovered by US researchers working in the 1960s. In fact, Henry Round at Marconi Labs noted the emission of light from a semiconductor diode 100 years ago and, ...

Optical sensors are a broad class of device for detecting light intensity. This can be just a simple component for notifying when ambient light levels rise above or fall below a prescribed level, or a ...

Abstract: An important issue faced while employing Pyroelectric InfraRed (PIR) sensors in an outdoor Wireless Sensor Network (WSN) deployment for intrusion detection, is that the output of the PIR ...

Abstract: This study focuses on image sensor communication (ISC), which is a form of visible light communication, using a light-emitting diode (LED) and a camera as the transmitting and receiving ...

Project Description This project uses YOLOv8 for object detection and an Arduino Uno (or Mega) to control an LED. If an electronic device is detected in the camera feed, the LED glows. The system ...

The SHT3x family of sensors should work up to 1 MHz I2C. This library should also work for SHT30 and SHT35 but these are not tested yet. Sometimes you need to control more devices than possible with ...

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 ...
