What it does
An open-source, 3D-printable automatic watering valve that measures soil moisture and opens or closes a motor-driven pinch valve to water plants only when the soil becomes dry, working with low-pressure gravity-fed sources (e.g., rain barrels) and pressurized systems up to 4 bar.
Who it’s for
Gardeners and hobbyists watering balconies, garden beds, raised beds, small greenhouses, community gardens, and rain-barrel systems, plus makers who want a repairable, modifiable open-source irrigation controller.
