## Long description

The Sonoff SONOFF-MS01 soil moisture sensor is a capacitive probe designed to work with Sonoff smart controllers such as THR16 and THR320 to monitor soil or substrate moisture. It provides real-time moisture readings and can be used to trigger irrigation or logging when connected to compatible Sonoff control units, helping automate watering and reduce manual checks.
Advantages
The SONOFF-MS01 offers capacitive humidity measurement across a 0–100% RH range, IP55 water resistance for use in planted environments, a compact probe size (130×30×13 mm) with a 50 cm cable and up to 10 m maximum extension, and low-voltage 3.3 V power supply requirements. Its compatibility with Sonoff TH-series controllers enables automated irrigation based on configurable moisture thresholds and supports voice queries through integrated smart assistant setups.
Suitable for
Home and indoor potted plants moisture monitoring
Automated sprinkler or drip irrigation systems controlled by Sonoff THR16/THR320

How to use
Connect the SONOFF-MS01 probe to a compatible Sonoff controller (for example THR16 or THR320) following the controller’s wiring diagram. Insert the probe into the soil or substrate near the plant root zone at the desired depth. Configure the controller’s moisture threshold and automation rules so that the relay activates irrigation devices when readings fall below the set value. Use the Sonoff app or supported smart assistant to view real-time moisture values and adjust settings.
Usage recommendations
Place the probe where it contacts the root zone for representative readings, avoid placing it in standing water, and use the IP55-rated probe outdoors or in humid environments while protecting the controller unit from direct moisture. For best results, calibrate threshold settings for your soil type and monitor initial readings after installation.
