I recently bought a Soil Moisture Sensor for my Arduino Uno from Amazon. The sensor was very easy to hook up and also easy to code.
The Arduino Code
I have written some sample code that outputs the readings to the serial console. I can run the code and watch the values change when in water, soil, and also when I hold the sensors in my hand.
You can see and get my code here on github. Feel free to add a comment with any questions.
If you want to get started at a very low cost ($6.55) and free prime shipping I recommend this soil hygrometer for your Arduino. There are all kinds of cool projects that could be made using the sensor.
Do you have this soil sensor? Leave me a comment below and let me know what you think or if you have any questions.
