Good sensor, needs tuning

Value for money is great. Had to adjust the threshold a few times to get accurate readings for my specific soil type.

Works but corrodes

Functionality is fine, but the probes show signs of rust after being left in soil for too long. Consider coating them.

Perfect for my Arduino project

Works exactly as described. Easy to calibrate the sensitivity potentiometer on the board. My plants are much happier now.
