From the project
Digital (RS485 - based) soil moisture and temperature sensor
A version of I2C soil moisture sensor with several updates - antistatic protection, local voltage regulation and RS485 networking.
This is a contact-less capacitive soil moisture sensor, a continuation of my I2C soil moisture sensor. This particular version of the sensor is suited for more professional installations where long cable runs is a requirement. It adds a local voltage regulator to mitigate the voltage drop and RS485 transceiver to accommodate long wires, also reverse polarity and an additional ESD protection level is added.
