Meet PlantSitter: a smart gadget that helps you take better care of your plants. It measures soil moisture, temperature, sunlight, and nutrition, enabling your plants to communicate with you when they need something. PlantSitter connects to your smartphone via Bluetooth (iOS or Android). It has a flash memory that can store up to 60 days of data.
PlantSitter is powered by a CR2032 battery. Its companion app lets you access your data in real-time or record it for future references. The product is expected to ship in September.[where to get it]
