いよいよ水分センサ。
コードはそのまま使います。（まずは準備）
————————-
Python sample code getting from Web
$ git clone git://gist.github.com/3151375.git
you find new directory “3151375”
In i tyou find python sample code “adafruit_mcp3008.py”
I will use this code itself.
before that, I need set up other package and so on.
Necessary Packages
$ sudo apt-get update
$ sudo apt-get install python-dev
Next, Install the latest RPi.GPIO module. We will use easy_install to manage the python packages.
$ sudo apt-get install python-setuptools
$ sudo easy_install rpi.gpio
Connect between RaspberryPi and this mousture curcuit.
Let’s get started!
$ cd 3151375
$ sudo python adafruit_mcp3008.py
————————-
結果は、
(1)taniku-pot-mad 355
(2)ko-cyou-ran case 422
(3)water case 501
(4)dry case 0
(5)shida-tree case 152
測定周期やＭｙＳＱＬ保存はこの次に。
はたして・・・
まずは、配線完了！！
（１）まずは、多肉植物、から。。
