Meet the PlantSitter: a smart plant monitoring system that lets you grow your plants like a pro. It has 4 internal sensors to measure soil moisture, nutrition, temperature, and sun light. It connects to your smartphone via Bluetooth. Thanks to this device, your plants will be able to tell you what they need.
PlantSitter will be compatible with iOS and Android devices. The battery lasts for hundred days. The flash memory is enough to store up to 60 days of data. Yet another interesting Kickstarter project.
