Description
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.
This is the easiest and the most robust way to read soil moisture and temperature values into Raspberry Pi. You can find the tutorial here.
Features:
- Capacitive soil moisture sensing
- Temperature sensing
