SONOFF WTS01 - Temperature sensor, Black

The SONOFF WTS01 Waterproof Temperature Sensor with RJ9 4P4C Connector is a wired probe for temperature monitoring through compatible SONOFF TH equipment. It measures temperatures from −40 °C to +115 °C, covering readings below freezing and at elevated temperatures. Accuracy is ±0.5 °C within the −10 °C to 85 °C range; that figure does not apply to the full measuring range. The sensor measures temperature, not humidity. Its waterproof design makes it suitable for use in humid environments.

The probe can be used indoors or outdoors where a compatible SONOFF TH device is installed. It relies on the connected control device to use its measurements, rather than operating as a standalone wireless detector. Its intended role is to provide temperature readings to that host, not to display them or sound an alarm. Plug-and-play installation requires no additional wiring or separate power supply. One sensor is included.

• Stainless-steel probe: provides the sensing element for temperature monitoring.
• 1.5 m cable: allows the probe to be positioned away from the connected device.
• RJ9 4P4C interface: connects to the compatible host device.
• Powered by the connected SONOFF TH device: requires no separate battery.
• Compatible with SONOFF TH Origin, TH Elite, THR316 and THR320.
