This is a simple arduino project for a soil moisture sensor that will light up a LED at a certain moisture level. It uses Arduino Duemilanove microcontroller board. Two wires placed in the soil pot ...

Since the project uses pretty basic components, the Arduino code is equally basic, too. It only has less than 50 lines and easily understandable functions and structures.

I also uploaded a simple test code to display sensor readings on the Serial Monitor window. I got some sensible sensor values (temperature, humidity and dew point). Although I didn’t expect it, the ...

You'll need an Arduino along with a bunch of various sensors to get the project rolling, and once it's all set up you'll have a simple, but cheap system to monitor your home. Head over to ...
