Here is a smart robot that not only waters your plants but also deters pests. GardenSpace detects how chlorophyll level, plant growth, and temperature change over time and make the data available on your smartphone. It also detects movements by animals and sprays to keep them away.
Each GardenSpace device can handle up to 100 sq. ft of crops. Simply connect it to your WiFi and water supply, and let the robot do the rest. Did we mention that the system is solar powered? Like what you see? You may want to back this project on Kickstarter.
