Most low cost soil sensors are resistive style, which tend to oxidize and require constant recalibration. The Adafruit STEMMA Soil Sensor uses a superior capacitive measurement wit h no exposed metal, providing reliable moisture readings without harming your plants.This sensor uses the ATSAMD10 chip's built-in capacitive touch system to measure soil moisture, giving readings from about 200 (very dry) to 2000 (very wet). Additionally, it provides ambient temperature from the internal temperature sensor (+/- 2°C accuracy).Featuring an I2C interface via a 4-pin JST-PH connector, it can easily connect to most microcontrollers and single board computers. Compatible with Arduino and CircuitPython, it's a no-solder sensor ready for your projects. Capacitive soil moisture sensing (non-resistive) Measures moisture from dry (~200) to wet (~2000) Ambient temperature sensing (+/- 2°C) I2C interface with JST PH 2mm 4-pin connector Compatible with Arduino and CircuitPython Small, compact form factor without exposed metal Note: This product includes the sensor only; a JST PH 2mm 4-pin cable is sold separately for connectivity.Refer to the full guide for wiring, schematics, and code examples.
