## Long description

Sonoff WTS01 waterproof temperature sensor with a 1.5 m cable and external probe provides remote temperature monitoring from -40°C to 115°C. Compatible with Sonoff TH Elite and Sonoff TH Origin relays (sold separately), the WTS01 is designed for use where a durable, corrosion‑resistant probe and flexible placement are required.
Advantages
The sensor delivers high accuracy within the common working range: ±0.5°C between -10°C and 85°C. Its probe is waterproof, corrosion- and rust-resistant, and connected via a 1.5 m cable to allow installation at a distance from the relay. The connector uses an RJ9 (4P4C) plug for direct compatibility with supported Sonoff relays.
