The analog output is clean and stable right out of the box, so I didn't have to fiddle with offsets. Plugged it into a simple ESP32 project and the readings changed noticeably within a minute after watering.

I hooked this up to my Arduino and the analog output gave me clear, precise readings. The corrosion-resistant coating on the probe is a nice touch for long-term use in damp soil.

Wiring it up took a bit of patience, but the analog output responds quickly when I poke the prongs into damp soil. It’s a solid, no-frills module for a weekend Arduino project, though the housing feels a little flimsy if you’re rough with it.
