(Continuation from yesterday)

Changing the subject,

It is said that a circulation board has a function to promote communications in a neighborhood unit.

However I am negative against this opinion. I think it will be useful as a detector of abnormal condition for "living alone", and very persuasive.

Even if it is useful, I am afraid that it means "too late" to find the abnormal condition, when the circulation board was not passed normally.

First of all, I am a distributor of the board, and I also distribute it once a month.

However, even if it is "too late", I think "to detect" might be meaningful.

Because, "both air temperature and humidity become high from now."

-----

In my opinion, I want to propose to install the following system,

"to observe "living alone" by human detection sensor"

"to send the detections to the NA-server"

and I want to manage the server by the community of the NA.

(Of course, persons who can say "I do not care about my privacy even if there is a human sensor", can use this system)

For me, I can realize this system just by 10,000 Yen as installation cost and 300 Yen as operation cost. (Three systems has already been working at our parent's house and my house).

The breakdown is that Raspberry PI(5000 Yen), soracom(6000 Yen) and human detection sensor(300 Yen) and monthly communication cost (300 Yen / month).

Based on 100 solitude houses, one year's MTBF, I can manage the systems as volunteer efforts of NA. At least, the cost might be cheaper than to manage circulation boards.

Of course, this monitoring service will be uninsured, because they are the volunteer efforts of NA.
