Description of the product: Adafruit Stemma - humidity sensor
The sensor used to measure the soil moisture and its temperature.Soldered and ready to connect, for example, to ArduinoorCircuitPython with the 4-pin wire through the I2C interface. The design of these sensors is based on capacitive measurement, it has not the bare metal so the probe is not oxidized when in contact with the soil anddoes not affect the current on plants.
The sensor has a built-in measuring system of the capacitive touch measurement built into theATSAMD10 system which gives readings in the range of from about 200 (very dry) to 2000 (very wet). In addition, it shows the temperature of environment from the internal temperature sensor on the microcontroller. It does not have very high accuracy, the measurement can vary up to +/- 2°C .
|VIN||The module's supply voltage in the range from 3 V to 5 V|
