 SMRT-Y Soil Moisture Sensor Kit

Turns any controller into a smart controller

It’s time for a little feedback from the roots. With the new SMRT-Y Soil Rainbird Moisture Sensor Kit, 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.

Makes any irrigation controller “smart”

Simple to use, yet highly sophisticated in what it does for water savings, the SMRT-Y Soil Moisture Sensor represents a new class of smart control technology. This affordable device precisely monitors moisture levels in absolute – rather than relative – terms, unaffected by soil temperature or electrical conductivity that limit the accuracy of other sensors.

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.

Water savings of 40% or more

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.

Advanced soil moisture sensing technology

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 also 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.
