The “Midori-San” is a system that allows a normal houseplant to write entries in a standard blog. In a similar way to its distant cousin, the “Botanicalls” project, the Midori-San uses surface potential sensors to read the bioelectric current flowing across the surface of the leaves. As the current fluctuates in response to environmental factors such as temperature changes, humidity, vibration, electromagnetic waves and nearby human activity an algorithm translates the data into sentences which are posted to the plant’s blog. Owners can subscribe to the plant’s blog to follow it’s story, and even earn the plant some cash by clicking it’s Google Adsense Ads. I guess money does really grow on trees.
