Corrosion-resistant capacitive soil probe with Gravity 3-pin interface. V2.0 fixes the old pain points (drift, noise sensitivity, connector quirks) for steadier, repeatable readings. Plug, read analog voltage, map to moisture—done. Highlights Capacitive sensing → no exposed metal, far less corrosion Works at 3.3–5 V (RP2040, ESP32, Arduino, etc.) Analog output (voltage increases with moisture) V2.0 improvements: better stability & noise immunity, cleaner baseline, sturdier build/connector Specs Property Value Interface Gravity 3-pin: AOUT, VCC, GND Supply 3.3–5 V DC Output Analog voltage, proportional to moisture Current Draw Low (single-digit mA typical) Sensor Type Capacitive (corrosion-resistant PCB) Compatibility Arduino, ESP32/C3/S3, RP2040/Pico, STM32, etc. Pinout Pin Function AOUT Analog output to MCU ADC VCC 3.3–5 V GND Ground What’s in the Pack 1× Gravity Capacitive Soil Moisture Sensor V2.0 1× Gravity 3-pin cable
