The SC-PROBE is a soil moisture sensor accessory that transforms the battery-operated NODE-BT controller into a smart solution that detects dry soil conditions at the root level and signals approval for the next scheduled watering cycle to run. If the soil moisture level is above the threshold indicated for watering, the irrigation cycle is suspended.

The SC-PROBE moisture sensor must be installed within 100' (30 m) of the NODE-BT controller using 18 AWG (1 mm2) direct-burial (UF) wire.
