Weather Sensor in Ground and Solar Sync in Sky

Built to Respond

The ultimate environmental solution.

Above & Below – Get the whole picture with the latest advances in water-saving technology. Pair our Solar Sync® with our new Soil-Clik moisture sensor to measure both climate and soil conditions. Solar Sync will use ET to adjust application amounts when irrigation is needed; Soil-Clik prevents watering when soil moisture levels have been reached. Together they’re the ultimate environmentally responsive solution.


Hunter has developed an extensive line of sensors to help monitor and adjust controllers through real time site readings. Let’s explore Hunter’s powerful sensor options and which ones are recommend as part of a smart controller.

Solar Sync Weather Sensor for Water Savings

Solar Sync – Weather Sensor

The Solar Sync ET sensor is an advanced weather sensor that calculates evapotranspiration (ET) and adjusts Hunter irrigation controllers daily based on local weather conditions. Solar Sync measures solar radiation and temperature, and uses ET to determine the correct seasonal adjustment percentage value to send to the controller. The controller then uses its programmed run time and Solar Sync's seasonal adjustment value to modify the irrigation run time for that day. In addition, the Solar Sync ET sensor includes the features of Hunter's popular Rain-Clik™ and Freeze-Clik® sensors providing quick response in shutting down your irrigation system during raining and/or freezing conditions.

Compatible with X-Core®, Pro-C®, ICC2, I-Core®, ACC, and ACC2 controllers

Smart Irrigation Control Made Simple

Soil Clik Moisture Sensor for Water Savings

Soil-Clik – Soil Moisture Sensor

The Soil-Clik simplifies soil moisture sensing. The Soil-Clik probe uses proven technology to measure moisture within the root zone. When the probe senses that the soil has reached its desired moisture level, it will shut down irrigation, preventing water waste. Soil-Clik is an effective water-saver either by itself or as the perfect companion to Solar-Sync.

Compatible with Hunter's X-Core®, Pro-C®, ICC2, I-Core®, ACC, and ACC2 controllers or any 24V AC powered controller

Flow-Sync – Flow Monitoring

The Flow-Sync is a simple and economical solution for metering and reacting to actual flow conditions. A proven water saver, the Hunter Flow-Sync connects to the ACC, ACC2, and I-Core controllers to measure actual flow, and provides automatic reaction to high or low flow conditions during irrigation.

Compatible with I-Core®, ACC, and ACC2 controllers
