What the Toro 53812 Actually Is
The Toro 53812 is the XTRA SMART Precision Soil Moisture Sensor, a wireless add-on that turns most standard irrigation timers into water-saving “smart” controllers. It is not a sprinkler or a spray head. Instead, it measures moisture at the root zone and tells your existing timer when to skip a scheduled watering, so it works alongside whatever sprinklers you already run rather than replacing them.
How It Works
A low-profile sensor probe sits flush with the soil and reads moisture continuously, sending readings wirelessly to a receiver wired inline with your irrigation timer. When the soil already holds enough moisture, or when freezing temperatures are detected, the receiver suspends the next cycle so you avoid watering a lawn that does not need it. Toro rates the wireless link at up to 500 feet line-of-sight, and the flush-mounted probe does not need to be removed before mowing.
Key Specifications

- Wireless range: Up to 500 ft line-of-sight
- Compatibility: Most standard timers, including Rain Bird, Hunter and Orbit
- Freeze protection: Suspends watering in freezing conditions
- Display: Large LCD showing sensor readings
- Installation: No digging or tools required
Where It Helps
The main draw is water savings. Toro states the sensor can cut annual water use by up to 35 percent by skipping unnecessary cycles after rain or during cool, damp spells. For anyone running a timer that waters on a fixed schedule regardless of weather, that is the single biggest efficiency upgrade you can add without replacing the controller, and it helps you stay within local watering restrictions.
Things to Keep in Mind
Because it is a sensor rather than a full smart controller, the 53812 only adds moisture-based skipping. It does not provide app control, zone-by-zone scheduling, or weather forecasting the way a Wi-Fi controller such as a Rachio does. A bypass mode lets you switch the sensor off for manual watering. Placement matters too: the probe should sit in representative turf, away from downspouts or low spots that stay wet.
Who It Is For
The Toro 53812 suits homeowners who already have a conventional irrigation timer and want to cut water waste without replacing their controller. If you are starting from scratch or want full smartphone scheduling, a dedicated smart controller is the better route. If you simply want your existing system to stop watering when the soil is already moist, this is an inexpensive, effective add-on.
