10 PCS Soil Hygrometer Detection Module – Moisture Sensor For Arduino – Open Box

If you're into Arduino projects or DIY electronics, grab this 10-pack of soil moisture sensors while they're available.

These are open box units, meaning they’ve possibly been tested or the box was opened, but they’re still in excellent condition and work perfectly.

Each one is a hygrometer detection module that reads moisture levels in soil—ideal for automated watering systems, plant monitors, or gardening experiments.

No brand name, just generic unbranded modules that do the job.

Perfect for hobbyists, students, or anyone building a smart garden setup.

Whether you're monitoring your houseplants or building a full greenhouse controller, these sensors give you reliable readings.

Ten pieces mean you can experiment, break a few, or build multiple projects without running out.

They connect easily to most Arduino boards and other microcontrollers.

Just plug them in, write a little code, and you’re tracking soil moisture in no time.

Great for STEM projects, hydroponics, or just keeping your tomatoes alive.

Get your hands dirty with electronics and gardening combined.
