Growth In The Internet Of Things Market – Business Insider

Growth In The Internet Of Things Market – Business Insider.

The Internet Of Things represents a major departure in the history of the Internet, as connections move beyond computing devices, and begin to power billions of everyday devices, from parking meters to home thermostats. 

Estimates for Internet of Things or IoT market value are massive, since by definition the IoT will be a diffuse layer of devices, sensors, and computing power that overlays entire consumer, business-to-business, and government industries. The IoT will account for an increasingly huge number of connections: 1.9 billion devices today, and 9 billion by 2018. That year, it will be roughly equal to the number of smartphones, smart TVs, tablets, wearable computers, and PCs combined.

Here is my first Thing.

It is also on Exosite and Thingspeak.



Radiation detection, Arduino and IoT (3)

The last version of this post is here.

The text bellow is obsolete and stays here only for historical purposes.


The third post, concerning this subject, consists only of a description of php script.

It does what it is supposed to do but I am convinced that there is a better (and elegant) solution to complete the task.

I choose to use an independent php script (that means that it runs by a command line and not under the web server control) similarly with a pearl or shell script

In fact it is a combination of two different php scripts because I need to sent data to two IoT platforms and, for this reason, I actually use two different methods stuck together in one script (no classes).

I am not happy with that solution so I made to myself the promise to change that code.

Here is that code. Continue reading

One (incomplete) map of Internet-of-Things

Take a look here (@thingful)

That’s an incomplete map of what looks like the World connected at Internet, the Things and not the Humans.

May be a not so objective image, because is still incomplete and do not cover all I-o-T platforms, but there still is a possibility to figure out how the World is connected.

An example: zoom in for Germany and you will be able to see how people are over there concerned of their energy consumption.

Radiation detection, Arduino and IoT (2)

The detection of radiation gives the need to measure it. Radiation detection yields pulses that are counted during a certain time (by minute, by hour, etc…). The amount found is converted in uSv/h (micro Sievert per hour).

Because I didn’t want to use a full Arduino, only to have counted the pulses sent by radiation detector, I actually use an Atmel ATtiny 45V controller that is doing very well in the role of Arduino. The main tasks of ATtiny so is to count the pulses sent by radiation detector during 10 seconds time period and send the value, by serial port, to the Big Brother (no, no, not That Big Brother!!!). This is my server that collects data around the house, keeps an eye on some places, listens and speaks over the Internet and so on… For this particular purpose there runs a script, written in php, that does the rest of the chores: calculates the radiation dose (represented in uSv/h from the value of  CPM – counts per minute – sent by ATtiny), saves the data locally on a file – together with the time-stamp -, sends it to the Cloud (Internet-of-Things platforms) where is visible (until now) on Exosite and Thingspeak.

To convince an ATtiny to play Arduino is possible as it is described in the arduino-tiny project, on Google-code.

Here are the schematics (ATtiny45 controller, RS232 adapter, Inter-connection cable).

The Arduino code for this job is here.

Radiation detection, Arduino and IoT (1)

These days is better to keep an eye on what happens around you. Not only economics, politics or weather changing but also radiation level. That is the goal for this post.

As my techno credo tells, to use, each time, whatever I have on hand and buy only when there is no other solution, as so I did here.

When the Fukushima  earthquake has brought, again, to world’s attention the radiations danger, the Internet was invaded by diggers for radiation stuff: the phenomenon, the detection, protection… A chilling recall of fifties and sixties when the danger was more political than this one: a combination of man-made and natural.

I found myself doing something, with more success than back in 1986, when, right after Chernobyl catastrophe, I did the same: looking for a radiation detector and I found it, eventually, with no Internet!

What I use now is an old and reliable Russian Geiger-Muller SI3BG buy-able on eBay (or other place). Looking around for stuff to match the intended application I found a dust gathering fancy light made for cars (you know, to put under the car to make it looking like a flying sauser, or so…). Inside of it is a dc-dc converter, from 12V to some high voltage, around 800V, necessary to power the glowing lamp. Applying  5V (not 12V) I was just obtaining 400V, the necessary voltage for my detector. Here is this schematic, with no details of what is inside of dc-dc converter but, out there, is plenty of this kind of schematics, on the Net.

Now comes the right moment to reveal the purpose of this project (it is almost clear from title, doesn’t it?): to be able to measure the radiation level at my venue (for the beginning indoor, during tests, and, eventually, outdoor) and to monitor it, by connecting the device to one, or another, of many  Internet-of-Things data platforms.

On Exosite  and Thingspeak you can see what the data is looking like. B.t.w. if you see nothing or it asks you to log-in, that translates as “Right now this is not public”.
