Ever thought of farm automation? Devon, from esologic.com loves tomato farming and his latest Raspberry Pi project allows for automation of the tomato farm. Well don't run your brains faster - because the system basically controls the water supply to the tomato mini-farm; but Devon's work on monitoring and collecting the data from the sensors would make it easier to add features to the system in future. We definitely like what Devon has achieved and have a video of the entire system in action.
The moisture sensors (see above photo) keep check on the soil in which the tomato plants are growing. But those are coupled with the temperature and light sensors as well. When the plants are at the seed stage, these sensors allow for the temperature control through heating mat. The light sensors would definitely be useful to provide the plants with the necessary light they need. The future setup may include a motorised bed which would raise the plants to the bulbs so that they don't have to works extra to get enough light.
Check out following video in which Devon explains the project in detail. We think this could be an interesting DIY or your third year mini-project using Raspberry Pi.
