Sprinkler Sensors

  Sprinkler Sensors help controllers shut off based on actual outside conditions such as rain, freezing temperatures, high wind speeds and over-flow conditions. Sensors help prevent costly and harmful over watering during unnecessary times or unfavorable conditions.

ET System uses sensors to determine the local "evapotranspiration" (ET) rate of turf and plants. This is a formula which calculates how much water the plants have lost, or consumed, due to local atmospheric conditions.

Each ET System can be customized by station (or "zone") for specific plant, soil, and sprinkler types. The result is a new, water-efficient irrigation program every water day, based on local weather conditions.

The Solar Sync continually gathers on-site solar and temperature data used in the calculation of evapotranspiration (ET), then determines watering requirements.

The Module automatically calculates water requirements and makes adjustments taking into account your regional weather characteristics.

Air temperature is monitored and used to calculate watering requirements. Too hot? Solar Sync knows to be efficient and waters your lawn as needed. Freezing morning? Keep those mittens off, because below 37° F, Solar Sync smartly waits for warmer temperatures.

Soil moisture sensors measure the water content in soil. A soil moisture probe is made up of multiple soil moisture sensors. One common type of soil moisture sensors in commercial use is a Frequency domain sensor such as a capacitance sensor.

Simply insert this rugged sensor in the soil to be tested and the volumetric water content of soil is reported in percent.

Rain sensors for irrigation systems are available in both wireless and hard-wired versions, most employing hygroscopic disks that swell in the presence of rain and shrink back down again as they dry out - an electrical switch is in turn depressed or released by the hygroscopic disk stack, and the rate of drying is typically adjusted by controlling the ventilation reaching the stack. However, some electrical type sensors are also marketed that use tipping bucket or conductance type probes to measure rainfall. Wireless and wired versions both use similar mechanisms to temporarily suspend watering by the irrigation controller - specifically they are connected to the irrigation controller's sensor terminals, or are installed in series with the solenoid valve common circuit such that they prevent the opening of any valves when rain has been sensed.

Rain/Freeze sensors are becoming "essential" components for any home or business irrigation systems these days.

A Rain/Freeze Sensor prevents your automatic sprinkler system from watering during a storm, cold weather.

Some irrigation rain sensors also contain the "FREEZE" sensor setting to keep the system from operating in freezing temperatures (typically freeze sensors are employed in regions where irrigation systems are not "blown-out" for the winter, yet there is sometimes a chance of overnight frost).


Wind Sensor data gathered or captured on any sprinkler’s performance chart is often gathered from tests conducted under zero wind conditions. However; in the real world; not every day is a tranquil one. Moreover; while most irrigation systems can still perform at close to peak efficiency with some type of breeze; when the air movement starts to get stronger; water coverage can get difficult; irractic and inevitably lead to run off... wasting our most precious resource.

The most cost-effective solution to such situations as it shuts off irrigation systems during periods of high wind (shut down points are adjustable); then automatically resets the irrigation system when conditions are more favorable. With a Wind Sensor you’ll save water and have peace of mind.

Real time climate information is essential for a Weather Station and can make for some tricky business when it concerns your irrigation system. Most people; can simply look out the window and decide whether to turn on the sprinklers manually each day; but that defeats the purpose of an automatic system.

What you really need is an automatic device "WEATHER STATION" that can make the decision whether there is too much rain; too much wind or too much cold to do the watering. With a Weather Station you get each of the three different sensor devices in one single convenient unit.

The "RAIN SENSOR" shuts sprinklers off in a storm and keeps them off; automatically compensating for the amount of rainfall that occurred. The "WIND SENSOR" shuts off systems during periods of high wind; then automatically resets the system when conditions are more favorable. The "FREEZE SENSOR" prevent your automatic sprinkler system from watering during a storm, cold weather.

Easy to mount (it attaches to your controller with just two wires) and easy to use; the Mini-Weather Station takes all the guesswork out of when you shouldn't water.

A homeowner can easily connect the most common type of rain sensor, a standard wired sensor device, to a typical 24-volt irrigation controller using simple hand tools and a ladder. Sensors with an electrical rating of 125-250 VAC for use with 110 or 220-volt controllers must be installed by a licensed electrician.

Each wired or wireless rain shut off device comes packed with instructions for a variety of installations--new, retrofit, same-brand, different-brand, sensor location, conduit, bare wire, with or without a bypass switch, etc.

Choose the best location for the sensor.
If the sensor is wired, try to find a location close to the controller. Consider how the wire will be run from the controller. The sensor should be in a location that closely matches ground conditions of the area it monitors. If the area is mostly shady, install in a shady location, but not directly under buildings or trees. If the area is sheltered from wind, then the sensor should be sheltered from wind as well. This is so that the hygrophonic disks (or cup) will dry at approximately the same rate as the soil. Ideally the sensor location should be chosen before the sensor is selected since various models come with unique mounting hardware.

Each wireless rain shut off device comes packed with instructions for a variety of installations--new, retrofit, same-brand, different-brand, sensor location, conduit, bare wire, with or without a bypass switch, etc. Here are some tips common to all installations:

The Wireless Rain Sensor conserves water by disabling a 24 VAC sprinkler system when rain is detected. The Wireless Rain Sensor consists of two (2) main components: a rain collector unit (the “Transmitter”) which senses rainfall and a receiver unit (the “Receiver”) which is wired into the irrigation controller. The Transmitter sends its signal wirelessly to the Receiver, eliminating the need for wiring. The user may adjust the sensitivity of the rain collector to rainfall levels between 1/8 inch and 3/4 inch.

The most important aspect of installing a rain sensor is where to place it. It should be installed in an area that is unobstructed by trees, roof over hangs, or anything else that might block rain from getting to the sensor. If it is a wireless sensor, placement is generally near the sprinkler controller. The should be connected inside the controller's valve wiring panel. This allows for easier electrical trouble-shooting of the system as the sensor can be easily disconnected.
