Built around an integrated Arduino Leonardo mainboard, it uses capacitive soil moisture sensors to detect when each plant needs water and activates a pump and four-way valve to deliver water precisely where it's needed.\n\nThis version adds a real-time clock (RTC) for scheduled watering and a 0.96″ OLED display showing the time and soil moisture status. The capacitive moisture sensors are corrosion-resistant for long service life — a significant improvement over traditional resistive sensors.\n\nKey Features\n\n\nIntegrated Arduino Leonardo – Built into the mainboard, programmable via USB\n\n4 Capacitive Moisture Sensors – Corrosion-resistant design for long-lasting soil monitoring\n\nAutomatic Watering – Pump and four-way valve deliver water to plants that need it\n\nRTC Timing – Schedule watering cycles with the onboard real-time clock\n\n0.96″ OLED Display – Shows time and soil moisture status at a glance\n\nUp to 4 Plants – Monitor and water four plants independently from a single system\n\n12V Power Supply – Single adapter powers the entire system\n\n\nSpecifications\n\n\nBox Size: 25×19×5.7cm\n\nWater Pipe Length: 5m (4×6mm)\n\nCrowtail Cable Length: 1m per sensor\n\nPower: 12V DC adapter (included)\n\n\nIdeal For\n\nAutomated indoor and outdoor plant care\nLearning Arduino programming with a practical project\nSmart garden and greenhouse monitoring\nHoliday plant watering while you're away\n\n\nPackage Contents\n\n1× Crowtail Smart Pump Shield v2.1\n4× Crowtail Capacitive Moisture Sensors\n1× 5m water pipe (4×6mm)\n1× DC 12V adapter\n1× DC 12V four-way valve\n1× Water pump\n4× 1m 4-pin Crowtail cables\n1× Five-way pipe connector\n1× USB cable\n\n\n\nNote: Please power the board with the DC adapter first when uploading new code via USB. This board is designed exclusively for the smart watering system.\n\n\nResources\n\nUser Manual v2.2 (PDF)\nSample Code (ZIP)\n","vendor":"Elecrow","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":4062,"title":"Default Title","sku":"EC-AAK90039K","price":86.33,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":1,"option1":"Default Title"}]}
