Because he was on holiday for two weeks and had no-one in the block of apartments
that he felt he could ask to look after his plants,
he devised a simple automatic watering system.
Basically, it consists of a container of water, a valve and a humidity sensor.
When the humidity sensor detects that the earth in the plant pot is too dry,
it causes a valve to open and release a fixed amount of water from the container into the plant pot.
As long as the earth is damp, the valve remains closed.
We also have in the pipeline a more sophisticated model which can be used all the time,
not just when you are away from home.
With a range of settings, it allows you to set Plant-carer to deliver exactly the amount of water indicated in the plant care instructions,
watering them as they need to be watered.
The result is that the average person can care for a plant as an expert would.
