1. An irrigation device for plants, in particular pot plants, of the type comprising:
a main body (100, 400); a tip (200, 110) adapted to be stuck into a plant substrate; an end fitting (404) opening upward from the body and adapted to tightly and removably cooperate with an opening of a bottle placed upside down, forming a water tank (B); and an irrigation means (300) provided in the main body, adapted to control a circulation of water between the end fitting (404, 405) and a water outlet passage (406),the device being characterized in that:
it further comprises humidity detection elements (202a, 202b) provided on the tip and an irrigation control circuit (700) connected to the detection elements; the tip comprises a generally planar and sharp blade-shaped part (200), locally coated with said detection elements (202a, 202b), an axis of the end fitting (404) being substantially aligned with a median axis of the blade-shaped part (200); and the irrigation means comprises an irrigation valve (300) controllable in response to instructions from the irrigation control circuit, so that the water flows from the water reserve (B) to go out through the water outlet passage (406) and to fall into the substrate. |
