Frequently Asked Questions

Q: Is this 4-way automatic watering DIY kit compatible with Arduino?

A: Yes! The kit is designed to work seamlessly with standard Arduino-compatible microcontroller boards. The Upgrade Set includes an Uno R3 board so you can start programming and testing your automatic watering system right out of the box.

Q: What is the difference between the Standard Set and the Upgrade Set?

A: The Standard Set includes the core components — 1 four-way relay, 1 water pipe, 4 soil moisture sensors, and 4 water pumps. The Upgrade Set includes all of these components plus an Uno R3 microcontroller board, a USB cable, and 30 Dupont cables (M-M, M-F, F-F) for easy wiring without soldering.

Q: How many plants can this automatic watering kit support?

A: This kit supports up to 4 individual plants simultaneously. Each soil sensor monitors one plant's moisture level and triggers its own dedicated mini water pump, providing independent, automated watering for each plant.

Q: Do I need any additional tools or components to set up this watering kit?

A: The Standard Set requires a compatible microcontroller board (such as an Uno R3) and wiring cables, which are included in the Upgrade Set. You will also need to write or upload watering control code to your board — basic Arduino examples are widely available online.
