Perfect for automation

Works flawlessly with my Arduino Uno. I set up a simple pump system and it triggers exactly when the soil gets dry.

Needed tweaking

Had to adjust code significantly for accuracy. Readings varied a lot until I stabilized the power supply.

Good value

Great sensor for the price but the probes corrode over time if left in soil permanently. Consider coating them.

Easy to calibrate

The potentiometer on the board makes threshold adjustment simple. No complex coding needed for basic use.
