The Optoelectronics group of Vishay Intertechnology, Inc. (NYSE: VSH) today introduced a new proximity sensor that offers a sensing distance of up to 30 cm. Combining an IR emitter, photo detectors for proximity, amplifiers, and ADC circuitry into a single package, the Vishay Semiconductors VCNL3040 features a programmable interrupt function and supports the I²C bus communication interface […]
Swedish and Chinese scientists have developed organic solar cells optimised to convert ambient indoor light to electricity. The power they produce is low, but is probably enough to feed the millions of products that the internet of things will bring online. For more information see the IDTechEx report on Energy Harvesting Microwatt to Megawatt 2019-2029. As the internet of things

Physical storage drives have not changed a lot over the years. They have improved in terms of storage capacity and technology but they are definitely still a bit bulky (compared with how small things are becoming) and relatively slow. To offer an improvement to what is currently in the market, GrowthLabs recently announced the launch of a

The nRF5340 is the world’s first wireless SoC with two Arm® Cortex®-M33 processors. It is truly secure, and the combination of two flexible processors, the advanced feature set, and an operating temperature up to 105 °C, make it the ideal choice for professional lighting, advanced wearables, and other complex IoT applications. The nRF5340 is an

everything is boring without LEDs, so lets make a city out of it! Basic Idea: so we build a City mode out of cardboard, then illuminate it with a LOT of RGB LEDs and let the temperature of color change according to room temperature using LM35 Temperature sensor. Supplies 1. WS2812b RGB LEDs (neopixels). 2.

A basic open-source multi-GHz sampling oscilloscope for experimenters on a budget. Still a work-in-progress, with key pieces on separate PCBs, but showing bandwidths in the 7-8 GHz range with >= 100 GSa/s equivalent-time sampling, and around 500 k comparisons/second real time. So far. Note: this writeup is somewhat out of date, as it doesn’t cover

This project simply switches the system OFF or ON whenever the temperature rises at the desired set point. The desired setpoint can be set using a fixed resistor R6 or PR1 trimmer potentiometer. Use any of at a time R6 or PR1. You can calculate the setpoint resistor R6 using the following equation: A relay
