You’ve read about it – now you too can follow your own pet vegetation on twitter! –
The Botanicalls Twitter kit includes all the hardware you need to create a networked communication system for your plant. A moisture sensor placed into the soil will send information to simple electronic detection circuitry you solder together yourself. Twitter updates are then sent out via an onboard Ethernet connection to the Internet, where they can be viewed online or routed to your mobile phone.
The pricetag seemed a bit a high before I realized all the hardware included in the kit – it even comes with an Arduino! – Botanicalls kit
Unfortunately, the dog still communicates via unfashionably messy methods.
