Sonoff Waterproof Temperature Sensor

This sensor features a stainless-steel waterproof probe that is rust-proof and corrosion-resistant, ensuring long-term durability in wet or humid environments. It replaces older 2.5mm jack models and is now equipped with an RJ9 connector, compatible with Sonoff TH Elite and TH Origin switches.

The sensor can be extended up to 60 meters using the RL560 extension cable, allowing flexible placement in remote or outdoor locations. It’s designed to detect and transmit temperature data to the eWeLink app, where users can set thresholds, create automation scenes, and receive alerts.

Whether you’re automating a greenhouse, monitoring water temperature, or integrating with smart irrigation systems, this sensor provides precise and stable readings for smart environmental control.
