2PCS Soil Humidity Sensor Module – Hygrometer Moisture Detection For Arduino, AVR – 3.3V-5V

Here's a 2-pack of soil humidity sensors—great for Arduino, AVR, Raspberry Pi, or any microcontroller project.

They detect moisture levels in soil and output an analog signal.

Each module includes both the sensor probe and the control board.

Made in China, unbranded, but super common in the maker community.

Works at 3.3V or 5V.

Great for automated plant watering systems, greenhouse monitoring, or just geeking out with sensors.

They come new, in anti-static packaging.

No fancy brand name, just gets the job done.

If you're building a smart garden or need backups for your bench, grab these.
