nano_iot (Part 1)

Part 1, 2

It has been quite a long time since my last posts on this blog. Many – hopefully good – reasons explain this prolonged silence. As I am a man of his words and because I am so curious and so fond of finding answers to all sorts of problems, I managed to be a municipal councilor in my town, on completion of a rough campaign which has been complicated by the covid 19 and all the restrictions in social life that this virus involved.

However, I am still active in the field of hi-tech, embedded systems, IoT. I have recently been invited at a round table at the MtoM IoT world in Paris, speaking about edge computing: “Where to process and analyze IoT data? How to distribute the capacities to do so? When should we decide on this? According to which model? Under what constraints?”. On the other hand, I kept working on the leanest possible IoT solution, using basic but rugged, cheap and easy to handle solutions. Which drove me to the concept of “nano-iot” networks, featuring “nano_iot_devices”, nano_iot_gateways” and “nano_iot_servers”. These works result in an effective local IoT network that I use extensively for performing all sorts of experiments inside and outside of my house. So far, I deployed various sensors such as temperature sensors (indoor, outdoor and freezer) , soil moisture sensor, air pressure, humidity and temperature sensor, power meter sensor.

Next is a plot of the latest electrical power consumption in my house:

A closer look at the plot shows the automated activation of the water boiler, the use of various appliances, the power peaks, many interesting information which may help to define the best price contract. I am waiting for colder days to establish a relationship between outdoor temperature and power consumption and then I will be able to get back to my provider as I suspect that my contract is not optimum… although they say that the smart meter will help them to improve their offer…

And now comes the time for a critical decision. 10 years ago now, I started Arduinoos with the intention of sharing my passion for technology, science and well being. As I am pretty broad minded, because I had a chance to meet people from many places around the world, I wrote all my publications in English. The statistics prove that I was right because arduinoos has fans from all around the globe. However, arduinoos fails to meet its closest potential french friends as not so many fellow countryman
and country woman are fluent in english. In addition to that, I feel very unpleased with the isolationism process carried out by the leaders in UK and US. That’s against the spirit of sharing, building bridges over humanity.

So that I am about to suspend, or close, arduinoos and start with a new blog (every thing is ready so far, name, domain, posts), featuring the same spirit and the same subjects. However, this blog will be written in french only. Before making this critical decision, I am looking forward to hearing from you about this decision…
