Sensor de temperatura Sonoff WTS01 con cable de 1,5 m, sonda externa para monitorización de temperatura

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.

Suitable for

• HVAC systems monitoring
• Refrigerators and freezers
• Aquarium and terrarium temperature control
• Server cabinets and electronic equipment enclosures
• Industrial or outdoor installations requiring a waterproof probe

How to use

Connect the RJ9 (4P4C) plug of the WTS01 cable to the Sonoff TH Elite or Sonoff TH Origin relay input. Place the waterproof probe in the location where temperature must be monitored, ensuring the cable routing does not stress the connector. After connection, configure the relay according to its manual to read and act on temperature values reported by the sensor.

Recommendations

Use the probe in environments within the specified temperature range and avoid mechanical impact on the probe and cable. For reliable long-term readings, secure the cable to prevent tugging and consult the Sonoff relay documentation for correct wiring and configuration.
