RAKwireless Soil Moisture Sensor

This is a soil moisture sensor kit with one sensor interface module that can be connected to up to three soil moisture and temperature sensors based on ATTINY441-SSU chip. The sensor is based on capacitive measurement and it’s coated sensor element makes it more reliable and longer lasting than sensors based on resistive measurement methods.

The calibration values are stored on the sensor element itself, so once a sensor is calibrated, it can be attached to any WisBlock Core module without the need to start a new calibration.
