Spectral signature is a characteristic property of a material that represent how the matter interacts with an electromagnetic radiation at different wavelengths. By looking at the reflectance spectra of a material, scientists can not only retrieve vital information like the chemical composition and crystal structure of the material, but also the presence of any impurities or third element within it.

Use of traffic navigation apps to minimize the wait time on road is very common for drivers these days. Google navigation gathers data from the drivers who are navigating via Google Maps and shows the traffic flow on smartphones in real time. While this is a great feature to have in smartphone, it would be nice

MQTT LED Matrix Display 7 Replies My MQTT network at home moves up and down a lot of messages: sensor values, triggers, notifications, device statuses,… I use Node-RED to forward the important ones to PushOver and some others to a Blynk application. But I also happen to have an LED display at home and that

Researchers have created a high voltage and high frequency silicon carbide (SiC) power switch that could cost much less than similarly rated SiC power switches. The findings could lead to early applications in the power industry, especially in power converters like medium voltage drives, solid state transformers and high voltage transmissions and circuit breakers. Researchers

Hello and welcome to my first Instructable. I will show you how to send emails from any ESP8266 wifi module using Gmail server. This instructable relies on Arduino core for ESP8266 WiFi chip, which makes a self-contained microcontroller from it (no need of AT commands and master devices). You can connect sensors and get notified

Web Bluetooth is a developing JavaScript API to allow websites to communicate with Bluetooth devices. Sites ask the browser to show a list of nearby Bluetooth devices matching certain criteria, and the user either picks which to grant access to or cancels the dialog. As you might expect, there are security risks here. When deciding

Story In this tutorial we will demonstrate how GPS data can be collected from a serial GPS module. We are using an Andoer u-Blox NEO-6M GPS module, which has excellent GPS capabilities. One of the NEMA sentences that it collects includes the GPGGA sentence which provides essential fix data. We’ll show you how to develop an application
