Great for my garden project

Works perfectly with my ESP32 setup. The capacitive design means no corrosion like my old resistive sensors. Highly recommended for automation.

No corrosion so far

Had resistive ones before that rusted in a week. This one has been in the soil for a month and still looks brand new.

Solid build quality

PCB looks nice and the gold plating gives confidence. Cable could be a bit longer but otherwise excellent.

Good sensor, needs calibration

Accurate once calibrated for your specific soil type. Took some time to get the thresholds right but works well now.

Easy to integrate

Plug and play with Arduino. The library examples found online work straight out of the box. Very satisfied.
