SMRT-Y Soil Moisture Sensor Kit Turns any controller into a smart controller
The Rain Bird SMRT-Y Soil Moisture Sensor kit adds closed-loop feedback to irrigation systems, conserving water through on-off system control based on digital measurement of the soil’s volumetric water content.
How It Works:
The sensor takes soil moisture readings every 10 minutes. When the sensor detects dry conditions prior to the normal watering cycle, that cycle is allowed. When the soil moisture is above the set threshold, the watering cycle is suspended to avoid wasting water.
Benefits:
Makes any irrigation controller “smart”
Typical water savings of 40% or more
Simple, reliable design with two main components (sold as a kit)
In-ground soil moisture sensor
Sensor control user interface
Advanced Time Domain Transmissometry (TDT) digital sensor enables highly accurate readings that are independent of soil temperature and electrical conductivity (EC)
User interface displays soil moisture content as well as soil temperature and EC
Automatic moisture threshold setting with increase/decrease adjustment
Sensor connects to an existing zone wire to simplify installation
No-maintenance sensor - just bury and forget

When soil moisture is above the established threshold, the irrigation cycle is suspended. When moisture falls below that level, the regular watering cycle is allowed.
