Integrated Sensor System™ (ISS)


Every golf course is its own complex ecosystem. To provide a consistent, playable environment, you need an accurate understanding of turf health. The Rain Bird® Integrated Sensor System™ (ISS) offers a snapshot of soil conditions to help you to understand what is happening below ground. It is also the only system in the industry to deliver easy-to-install absolute soil sensing and full integration with the central control system. As a result, you’ll save more time, water and money with Rain Bird.


Dynamic integration. Fully automatic.
When paired with a Rain Bird Central Control System, the Integrated Sensor System can automatically adjust sprinkler run times to reach maintain desired moisture levels, minimizing water consumption, resulting in healthier turf and better playing conditions.

Intelligent monitoring. 
As a standalone system, the ISS analyses soil moisture and calculates water budget recommendations for any golf course.

Maximum accuracy. 
Zero calibration. The ISS uses research-grade soil sensors backed by years of field experience. These sensors have been vetted by multiple academic peer- reviews. The ISS takes highly accurate readings of soil moisture, salinity and temperature immediately following installation and without calibration – for easy installation and immediate accuracy.

Adjustable soil sensing rate. 
With the Rain Bird ISS, the frequency of soil sensing measurements can be adjusted to match course needs.

Dependable results. 
Sensor readings are automatically stored by the data logger on Secure Digital High Capacity (SDHC) storage cards. Data is not lost due to power outages or wireless communication issues.

Dependable communication. 
The ISS uses a proven wireless mesh network which ensures the necessary range of transmission and a secured traffic from the data logger to the Soil Manager™ software.

Simple installation. 
Network devices (data loggers and repeaters) are battery-powered and easy to install. There is no AC power source to worry about.

Improves turf health, course consistency and playability.
The ISS can help deliver more consistent turf quality, anticipate plant stress, weed germination, pest infestations and other factors. You can use less water to flush salts from the soil profile.
