Developing a Smart Android App for Temperature Alert System This project presents an Android app to generate an alert (alarm) on a smartphone when the temperature of the process under consideration exceeds user-defined maximum temperature. Alarm and annunciator instrumentation systems are widely used in the control room of process plants. When process variables being monitored by various on-field sensors exceed maximum/critical value, an alarm is generated on the PC or annunciator in the control room. This helps notify the operator to take necessary action to avoid any industrial disaster. This project is a smart temperature alert system based on a customised Android app,  Arduino  Uno and Bluetooth. The authors’ prototype of the project is shown in Fig. 1. Fig. 1: Authors’ prototype wired on breadboard Circuit and working The circuit diagram of the Android app for an over-temperature alert is shown in Fig. 2. It is built around Arduino Uno board (Board...

Dev Board With Splendid Functionalities For High-End Applications The PICO-WHU4 computing platform comes with a much more powerful processor which can be considered a suitable alternative to Raspberry Pi The PICO-WHU4 (Image credit: www.aaeon.com) Raspberry Pi is one of the most popular development boards out there. After all, it offers DIY enthusiasts a platform to create simple to complex electronic projects while consuming less time, energy, and money. Now, a development board that is much more powerful than the newest Raspberry Pi board is set to change the game. Presenting the PICO-WHU4, a compact single-board computer built for AI and Edge computing by AAEON. As compared to Raspberry Pi’s most enhanced offering, the Raspberry Pi 4 that has Quad-core Cortex-A72 (ARM v8) 64-bit SoC, the PICO-WHU4 is equipped with 8th Generation Intel® Core and Celeron® processors that are available in four variants: i7-8665UE (1.7GHz up to 4.4GHz), i5-8365UE (1.6GHz up to 4.1GHz), i3-814...

Eco-Friendly Polymer-Based Thin Film For Printed Electronics The polymer thin film is also robust to high temperatures and highly flexible, making it great for developing electronics that are light and have a very little negative impact on the environment. A hyaline thin film (Image credit: www.zymergen.com) Manufacturing of electronic products and their improper disposal is often counted as one of the reasons for environmental damage. Despite deriving several key elements such as lead, nickel, arsenic, barium and many more from nature, prolonged exposure to such heavy metals is known to cause severe health issues and atmospheric deterioration. And at the same time, electronics are indispensable for spearheading the technological revolution. It’s an ongoing dilemma. To tackle this problem, manufacturers are gradually promoting green electronics, which consists of identifying and incorporating biodegradable elements into electronic products. Although it is an emerging field...

A boy with a monstrous secret waits in the wings. Together, they must assassinate the king and stop the war. In a centuries-long war where beauty and brutality meet, their three paths entwine in a shadowy world of spilt blood and mysterious saints, where a forbidden romance threatens to tip the scales between dark and light. Wicked Saints is the thrilling start to Emily A. Duncan’s devastatingly Gothic Something Dark and Holy trilogy... ...... My Review: “We're all monsters, Nadya, some of us just hide it better than others." ” A character-driven story. The best thing about this book is the characters. Talking about the characters may make this review a little spoiler, but they were so diverse, so beautifully constr...

Designing Android App For Communication With Bluetooth Module This article is about designing an Android app for communication with HC-05 Bluetooth module using MIT App Inventor (open source), a block-based programming tool. MIT App Inventor is used to create apps without any text-based programming language or bulky software in your PC. Arduino Uno board along with a Bluetooth module and an LED is used for testing the app. In this project we're gonna use MIT app inventor..!!
