Hackathon project that automatically waters plant when it gets "thirsty".
Using a mobile site a plants soil humidity is measured and it can be remotely watered. A soil sensor and water bucket servo are hooked to an Arduino. The Arduino displays the soil humidity on a LED strip and actuates the servo on button press or on API call.
A static mobile site communicates to the Arduino's REST server. The mobile site/app allows a user to define a plant, location and name it. It shows the soil humidity in real time and allows watering with a simple button press.
