SMRT-Y Soil Moisture Sensor
SMRT-Y Soil Moisture Sensor
Accurate - Reliable - Smart
It’s time for a little feedback from the roots. With the new SMRT-Y Soil Moisture Sensor Kit from Rain Bird, an irrigation controller is directly linked to the absolute moisture requirements of a site’s vegetation.
When the sensor detects dry conditions, the next scheduled watering cycle is allowed. If a site’s soil moisture level is above the threshold, the irrigation cycle is suspended. There are just two basic components: an in-ground sensor and a user interface at the controller.
- Turns any controller into a water saving smart controller
- Healthier landscapes less prone to nutrient depletion, fungus, and shallow root growth
- Typical water savings exceed 40%
- TDT digital sensor enables highly accurate readings that are independent of soil temperature and electrical conductivity (EC)
- Displays soil moisture content, soil temperature and EC
- Corrosion-resistant in-ground sensor made of high-grade 304 stainless steel
Key Benefits
- Proven Water-Savings. An independent research study proves that a SMRT-Y delivers 45% to 73% water savings.
- 20 Minute Installation. Perfect for contractors who are looking for a water-saving upgrade solution for their customers – with minimal installation time.
- Makes Most Any Controller Smart. Works with any standard 24V AC controller, the SMRT-Y Sensor allows watering based on the soil's actual moisture content. Note: not compatible with 2-wire controllers.
- Bury and Forget. Made with high grade 304 stainless steel – not plastic resin – the SMRT-Y Sensor has been rigorously tested for over five years in the harshest conditions for trouble-free performance.
- Industry’s Most Accurate Sensor. The SMRT-Y digital TDT™ sensor is highly accurate in any soil condition with no manual calibration needed.
Advanced TDT Digital Soil Moisture Sensor
- Sensor uses Time Domain Transmissometry (TDT) and digital signal processing to measure soil moisture content accurately and consistently
- Corrosion-resistant in-ground sensor made of high-grade 304 stainless steel
- No maintenance sensor – just bury and forget
- Reads absolute – rather than relative – Volumetric Water Content (0-100%)
- Moisture readings remain stable as soil salinity and temperature change
- Sensor never needs calibration
User Interface with LCD Readout
- Touchpad keys with digital LCD readout displays:
- Absolute Volumetric Water Content, 0-100%
- Soil temperature in Fahrenheit or Celsius
- Soil conductivity in dS/m
- Seven-cycle irrigation history
- Suspended/allowed watering indicator
- Bypass mode indicator - Automatic moisture threshold setting with increase/decrease adjustment
- Sensor bypass touchpad key for easy deactivation
- Up to two independent zones can be isolated from sensor
- Designed for outdoor installation
