Vendor: Rain Bird
Type: Controller
Price: 221.00

The Rain Bird SMRT-Y Soil Moisture Sensor kit converts a standard irrigation controller into a closed-loop, water-saving system. Using a digital TDT probe and a compact controller interface, the SMRT-Y measures soil volumetric moisture, soil temperature and electrical conductivity (EC) to suspend or allow scheduled watering and reduce overwatering.

Digital TDT in-ground probe provides precise volumetric water content readings independent of soil temperature and salinity (EC).

Displays soil moisture (0–100%), soil temperature (°F/°C) and EC on a touchpad LCD; seven-cycle watering history is saved.

Automatic moisture-threshold setup with manual increase/decrease and a sensor bypass key for easy deactivation.

Corrosion-resistant in-ground probe manufactured from high-grade 304 stainless steel for long outdoors service; designed to be “bury-and-forget” with no calibration needed.

Sampling every 10 minutes and suspends scheduled cycles when the measured moisture is above threshold, delivering typical water savings over 40%.

Includes controller interface, in-ground sensor, anodized stainless screws, wire nuts and multilingual manual for straightforward installation.

The compact controller interface measures 3.0" (76 mm) wide × 3.0" (76 mm) high × 0.75" (19 mm) deep. The in-ground probe measures approximately 2.0" (50 mm) wide × 8.0" (200 mm) long with 18 AWG leads about 42" (107 cm) long. Operating power is supplied by the controller (25 VAC at 12 W); operating temperature range is -4°F to 158°F (-20°C to 70°C) with survival ratings to -40°F to 185°F (-40°C to 85°C). The SMRT-Y kit is compatible with most standard irrigation controllers and can isolate up to two independent zones from sensor control when required. Refer to the included technical specs and manual for wiring diagrams, threshold-setting procedures and recommended probe placement depths.
