As we know, IoT is popular technology which name represents “internet of things”. The number of IoT devices increasing day by day. So, I am keen on this area. I want to control and edit home devices via Arduino, raspberry pi or other cards.
We can control all home devices or we can convert all devices a part of IoT. We need sensors according to our needs and programming knowledge. Do not worry :) I'll talk about simple arduino devices.
Firstly, I want to control plants in my home, I’ll use my Arduino Uno, because no need to more specific cards. Arduino is suitable for beginners, arduino uses low energy that no need to much cpu power, It is suitable for his work. Let’s start my work;
If ground has water, as we know water conduct the electric, (electrons can be flow in water molecules) but drought ground can’t conduct the electric. Ground is dielectric and infinitive neutral. That’s the working principle my Arduino censor.
