[00:01.27]Because he was on holiday for two weeks and had no-one in the block of apartments
[00:05.47]that he felt he could ask to look after his plants,
[00:08.56]he devised a simple automatic watering system.
[00:12.82]Basically, it consists of a container of water, a valve and a humidity sensor.
[00:19.77]When the humidity sensor detects that the earth in the plant pot is too dry,
[00:25.17]it causes a valve to open and release a fixed amount of water from the container into the plant pot.
[00:32.06] As long as the earth is damp, the valve remains closed.
[00:36.87]We also have in the pipeline a more sophisticated model which can be used all the time,
[00:42.15] not just when you are away from home.
[00:44.90]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,
[00:53.85]watering them as they need to be watered.
[00:57.46]The result is that the average person can care for a plant as an expert would.
