Automatic plant watering device

This device may be useful for florists and other who like green environment at home but forget to water them regularly to water them. So why not to automate this process with simple embedded system which controls water pump. Device as design project was developed by student Gang Xie in Stanford University.

Device not only waters plant regularly but has a real time clock for exact time counting, LCD which displays time and system states, speaker for alarming, push buttons for changing states and time. Microcontroller controls water pump through relay. Project software is written in AVRGCC C language. Design could be improved by adding humidity of soil reading through ADC channel.
