The Arduino Automatic Smart Plant Watering Kit 2.1 is a complete system for monitoring and watering up to four plants automatically. 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.
This 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.
Key Features
- Integrated Arduino Leonardo – Built into the mainboard, programmable via USB
- 4 Capacitive Moisture Sensors – Corrosion-resistant design for long-lasting soil monitoring
- Automatic Watering – Pump and four-way valve deliver water to plants that need it
- RTC Timing – Schedule watering cycles with the onboard real-time clock
- 0.96″ OLED Display – Shows time and soil moisture status at a glance
- Up to 4 Plants – Monitor and water four plants independently from a single system
- 12V Power Supply – Single adapter powers the entire system
Specifications
- Box Size: 25×19×5.7cm
- Water Pipe Length: 5m (4×6mm)
- Crowtail Cable Length: 1m per sensor

Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- OLED
- OLED stands for organic light-emitting diode, a display type where each pixel produces its own light. It matters because OLED screens are thin, high-contrast and easy to read for small status displays, but they can be more sensitive to image burn-in than some other display types.
- RTC
- A Real-Time Clock keeps track of time even when the main processor is asleep or powered down, usually with a small backup battery. It matters for data logging and tracking projects that need accurate timestamps.
- Shield
- An add-on board that plugs into a main controller board to give it extra features such as sensing, motor control or communication. Knowing a product supports shields helps you judge whether it can connect neatly into an existing maker-board setup.
