Professional rain sensor installation services
A rain sensor is a small weatherproof device, mounted on your roofline or near your sprinkler heads, that talks directly to your irrigation controller. Once it detects enough rainfall, it interrupts the watering cycle — then re-enables itself automatically once things dry out.
For Gainesville homeowners, this isn’t just convenience. Alachua County requires every automatic sprinkler system to have a working rain sensor installed, so a missing or broken one can put your property out of code, and it’s one of the fastest ways to waste water on an already-saturated lawn.
We install both wireless and hard-wired sensors, matched to your controller brand, mounted in full rain exposure, and calibrated to your landscape’s real watering needs.
Benefits of installing a rain sensor
Lower water bills
Lower water bills hover for detail
Skipping cycles after rainfall is one of the simplest ways to cut monthly water costs during Florida’s wet season.
Healthier lawn
Overwatered turf is prone to fungus and shallow roots. A rain sensor helps grass grow deeper, drought-resistant roots.
Code compliant
Automatic sprinkler systems in Alachua County must have a working rain sensor. Installation keeps you inspection-ready.
Longer system life
Less unnecessary run time means less wear on valves and sprinkler heads — fewer repairs down the road.

Frequently Asked Questions
What does a rain sensor do for a sprinkler system?
A rain sensor automatically shuts off an automatic irrigation system when it detects a set amount of rainfall, then re-enables watering once conditions dry out — preventing the system from running during or right after rain.
Is a rain sensor required by law in Gainesville, FL?
Yes. Alachua County requires all automatic sprinkler systems to have a working rain sensor installed as part of local water conservation code.
How much does rain sensor installation cost?
Cost depends on your controller type, whether you choose a wireless or hard-wired sensor, and your property’s wiring access. We provide a free, no-obligation quote after a quick assessment.
Can a rain sensor be added to an existing irrigation system?
In most cases, yes. Rain sensors are compatible with the vast majority of controllers already installed in Gainesville-area homes and can typically be retrofitted without replacing the controller.
Wireless vs. hard-wired rain sensor — which is better?
A hard-wired sensor connects directly to your controller with a cable, while a wireless sensor communicates via signal to a receiver. Both work the same way — the right choice depends on your property’s layout.
How long does installation take?
Most installations are completed in under an hour and are typically finished the same day as the service visit.
How much rainfall triggers the sensor?
Sensors are calibrated to a threshold, usually between 1/8″ and 1/4″ of rainfall, so light dew or humidity won’t falsely trigger a shutoff.
Do rain sensors need maintenance?
Occasional cleaning and periodic testing keep a rain sensor accurate. We check rain sensor function as part of routine sprinkler system inspections.
