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.
