Soildrops Moisture Sensor

Moisture Sensors

AI-Powered Scheduling

Utilizes real-time local weather data and soil moisture levels to automatically adjust watering schedules.

Real-Time Data

Sensors penetrate 6 inches into soil to deliver precise moisture readings and transmit real-time data.

Long Life Span

Sensors have a battery life of ~2 years and replaceable batteries, so you won’t have to worry about replacing the sensor itself.

Mower Friendly

Sensors extend just 1.5 inches above the soil, allowing you to mow over them without any damage.

Frequently Asked Questions

What does the Soildrops Soil Moisture Sensor do?

It measures real-time soil moisture in each irrigation zone and sends the readings wirelessly to your Soildrops Controller. With sensors paired, the controller switches to Autopilot mode and waters only when the soil actually needs it.

How accurate is the sensor?

±3% volumetric water content under normal conditions — accurate enough for residential irrigation decisions. It's calibrated for typical soil and is most reliable when buried at root depth.

Where should I place the sensor?

In the center of a sprinkler zone, or under a drip emitter at the midpoint of a dripline zone — roughly one-third of the way out from the nearest sprinkler head. Push it into moist soil at root depth (about 3–4 inches for lawn, deeper for shrubs and trees) until it's flush with the soil surface. Avoid zone edges, soggy spots, concrete or rocks, and sloped low points where water pools.

How long does installation take?

About 3 minutes per sensor — no tools required.

Do I need to remove sensors before mowing?

No. They sit flush with or slightly below the soil. If you're scalping or dethatching, mark them with a flag so you don't catch them with a blade.

What's the wireless range?

Up to ~100 ft in open air, and 60–80 ft through a house. If you need more range, the Soildrops Booster doubles signal range to 300+ ft. Place the booster within 50 ft of the sensor.

How long does the battery last?

1–2 years on a single CR2032 coin cell. The app shows a yellow indicator when battery is low and a red one when it's time to replace.

Are the sensors waterproof?

Yes — they're fully waterproof and designed to live in wet soil year-round.

How do I pair a sensor to my controller?

Hold the sensor's button for 5 seconds until the LED blinks. In the app, tap Add Sensor and scan the QR code. A 0% reading right after pairing is normal — accurate readings come in within ~10 minutes.

How do I know my sensor is working?

In the app, a healthy sensor shows a current moisture reading, a green signal indicator, and a healthy battery icon. The moisture % should rise after watering or rain and gradually fall as the soil dries.

How do I reach customer service?

Our customer service team is available Monday–Friday, 9am–5pm Pacific Time.
