The SMRT-Y Soil Moisture Sensor is an affordable device that precisely monitors moisture levels in absolute terms, unaffected by soil temperature or electrical conductivity.

Relaying that information back to the controller, it only allows a watering cycle when the root zone moisture drops below the set threshold. Based on the same TDT* sensing technology developed for agricultural applications, the SMRT-Y soil moisture sensor’s long-lasting dependability addresses the environmental demands of both residential and commercial applications.

By optimizing the amount of moisture at the root zone, the SMRT-Y conserves enough water in many applications to pay for itself in less than a year. Avoiding the tendency to overwater, you will enjoy a healthier, lush landscape that is less prone to fungus and shallow root growth.

The device eliminates needless watering and lets the soil say when watering is appropriate. Adding a soil moisture sensor allows you to meet many toughening water conservation guidelines that call for ‘smart’ watering devices.


  • Checking soil conditions every 10 minutes, the SMRT-Y displays moisture content, electrical conductivity and temperature of the soil, all at the touch of a button.
  • The device provides watering history for the last 7 irrigation cycles.
  • With soil moisture sensing, you no longer need to be concerned with adjusting the controller. Just program the controller one time to water every day that irrigation is allowed – the soil moisture sensor will do the rest.
  • As the SMRT-Y optimizes moisture at the root zone, you will enjoy a lush, healthier landscape that is less prone to fungus and shallow root growth.
  • By eliminating overwatering the SMRT-Y saves water, typically over 40%, paying for itself in less than a year.
  • Suitable for residential and commercial applications.
  • The SMRT-Y connects to an existing zone wire and never needs calibration or batteries. Simply connect, bury and forget.
