Graygarden: Self Watering, Soil Moisture Sensing, Planter

thingiverse

This self-sustaining planter leverages a soil moisture sensor in conjunction with an Arduino UNO to continuously monitor soil hydration levels, seamlessly activating a built-in water pump when the soil reaches dryness. The accompanying Arduino code is meticulously straightforward, making it easily understandable even for individuals without prior coding experience, allowing them to intuitively modify parameters such as watering duration per session, optimal soil moisture thresholds for activation, and sensor check frequency. The design boasts a simplistic yet effective aesthetic, comprising three intricately nested cylindrical sections: the lower compartment houses a water reservoir and miniaturized pump, while the middle section accommodates key components, and the uppermost part serves as the soil container. A comprehensive Arduino sketch is provided in both Word document and .ino file formats for convenient reference and customization.
