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
  • Good stability with temperature
  • Good stability with power variation
  • Suitable for long cable runs
  • Uses industrial Modbus protocol
  • Low current consumption in deep sleep mode - 11 uA


Technical Data:

  • Supply voltage: 5V
  • Bus can be run on both 3V and 5V
  • Default serial settings: 19200, 8-bit frame, no parity, 2 stop bits
  • Default Modbus address: 1
  • Current consumption: Active: 9 mA, Deep sleep: 11 uA
