SONOFF MS01 Soil Moisture Sensor (RJ9)

Description

The SONOFF MS01 Soil Moisture Sensor is designed to accurately measure soil moisture levels and enable smart irrigation automation when connected to compatible SONOFF devices. When paired with SONOFF TH Elite or TH Origin smart switches, the sensor monitors soil moisture in real time and sends the data directly to the eWeLink mobile app.

This smart sensor allows you to create an automated watering system for gardens, plants, lawns, or greenhouses. When the soil moisture drops below a preset level, the connected irrigation system can automatically activate, ensuring plants receive the right amount of water without manual monitoring.

The MS01 uses a capacitive sensing design to provide stable and accurate readings while avoiding corrosion that can occur with traditional probes. Its IP55 waterproof rating allows the sensor to remain outdoors even during watering or rain, making it ideal for long-term garden or greenhouse monitoring.

Installation is simple thanks to the RJ9 plug-and-play connector, allowing the sensor to connect directly to compatible SONOFF devices. The included cable provides flexible placement so the sensor can be positioned directly in the soil where moisture measurements are needed.

Whether you’re managing a smart garden, greenhouse, irrigation system, or plant care setup, the SONOFF MS01 makes it easy to automate watering and keep plants healthy with minimal effort.
