Introduction There are plenty of features to explore in IoT; this post starts with the analog side. The ability to handle analog I/O is attractive for IoT wireless sensor node use to make use of many of the interesting sensors out there.   Often analog sensors need to be interfaced, however many sensors (such as thermocouples or photodiodes) output tiny voltages or currents. When designing IoT devices, it may be desirable to replace the sensor with a fixed voltage source or current sourc ...
In Old meets new, the 1-Wire Weather Station on the SPARK Core. (part 1) I described the motivation of the project. This part will focus on the first steps of programming the SPARK Core and interfacing it to the 1-Wire bus. I don't repeat the information which can be found on the spark.io website and user forum, just a description of what I did to get the project going and some opinions about the spark.io system.   Although the SPARK language is almost similar to Arduino, it can not be pr ...
Prelude - Age industrial age  The industrial age came about with the advent of the desire of people to live better lives and have access to facilities. These higher standards of living were attained by the use of machines and chemicals and so the agricultural society was slowly supplanted by the Industrial one. People moved to careers in the industry which was based on production of all kinds of things from electricity to electric products, from transportation and construction to consumer ...

The Features of IoT

Posted by shabaz Top Member Nov 23, 2014
Introduction A recent topic of conversation discussed whether there was a need for IoT devices to have sensors or not. Points were raised that many features were important. For example the ‘smart objects’ view is a less sensor-centric view, where the smart object can have sensors attached. What then are the features of IoT in general? After studying dozens of IoT labelled solutions, there were many common features that appeared again and again. It was decided to try to document them, ...
In 2014 might have started a revolution in the Internet of Things. New ESP8266 Wi-Fi modules are tiny, cost less than 5 USD and take care about Wi-Fi connection and encription in Access Point mode and in client mode.  Communication to the module is via simple serial RX and TX lines using "AT" type commands and data. ESP8266 is intended for use in smart power plugs, mesh networks, IP cameras, wireless sensors, wearable electronics, etc. It is based on 32-bit processor Tensilica’s L10 ...

IoT Lives!

Posted by doctorcdf element14 Team Nov 17, 2014
There has been a bit of chatter this week that the Internet of Things, or at least the three letter acronym IoT...is dead. Indeed our friends at Electronics Weekly wrote a comment piece this week "IoT RIP" which kind of suggests it might be. Now I don't want to upset anyone but when I was at Electronica, I saw no indication that the days of the IoT acronym were numbered. On the contrary, it was all IoT all the time. I did see evidence that the technology is moving from the "hype" phase to the ma ...
NOTTI smart-light (via Witti) Witti Inc. is a group of savvy designers that created something simple, beautiful, and effective. No wonder their Kickstarter campaign is through the roof! You can get one for about $40 if you act fast. Their product is called the NOTTI, and it's a smart-light that syncs to your phone to gently notify you of text messages, phone calls, emails, and more. It also has a special alarm clock feature that gently wakes you up by progressively brightening the room 5 mi ...
Almost 15 years ago I worked on an Internet of Things project. Yes, I know, the IoT concept wasn't used by then, but the technology was there. The device I used was the TINI (Tiny INternet Interface), a product of Dallas Semiconductor, which company later was acquired by Maxim. The "board" was a 68-pin SIMM that is approximately 103 mm wide, 32 mm tall running Java. There was a small unix like operating system and even a web server. Believe me or not, I still have a door lock with access contr ...
ST is today introducing a new innovative approach making our global portfolio available to our customers in an easy to use, affordable way. STM32 Open Development Environment is the answer to the market need allowing to quickly prototype, develop and industrialize solutions for innovative markets such as the Internet of Things, enabling customers to access the broad rich portfolio of IP available in ST. in brief STM32 Open Development environment is the openf flexible easy and affordable way to ...
Currently I am playing with the ESP8266 WIFI module as many others are. Since I want to create some Arduino libraries for it, I am in the need to do some debugging. The Arduino only has one hardware UART. And if you wire anything to the atmega UART port you may run into problems when downloading new code to the Arduino. The Arduino programs the atmega via the hardware UART port and if something is connected it may cause trouble. For downloading you end up disconnecting and reconnecting the ESP m ...
Introduction The information that is gathered from sensors in its raw form or processed, can be priceless. Results may have taken days to obtain, so data loss can be catastrophic.   One general rule would be to get the data off small embedded devices as soon as possible, and back it up, perhaps store it in redundant data centres, and a cost-effective way of doing that is to make use of cloud offerings.   However, network connectivity is not always feasible for all use-cases.
