The SONOFF MS01 Smart Soil Moisture Sensor helps you monitor soil hydration in real time, ensuring your plants receive the right amount of water. When paired with a SONOFF smart switch (such as TH Elite or TH Origin), it enables fully automated irrigation based on moisture levels—perfect for home gardens, greenhouses, and indoor plants.
Example use
Place the MS01 in your plant soil and set a moisture threshold—when the soil gets too dry, your SONOFF smart switch can automatically activate a pump or watering system to keep your plants healthy without manual checks.
