Tillun is a little device which helps a gardener visually tell the hydration
|
|
level of his plant's pot. With this information, the gardener can decide if he
|
|
should water the plant or not, and also if he watered the plant enough.
|
|
|
|
_Note: you could wonder: can't the gardener obtain the same information by
|
|
taking a look at the pot's soil or sticking his finger in it? Absolutely. This
|
|
project is just a fun, unnecessary endeavour executed in the most professional
|
|
way possible._
