The Sonoff WTS01 outdoor and indoor waterproof temperature sensor is a digital temperature sensor with a calibrated digital signal output. Thanks to its water resistance, it can also be used reliably in wet rooms or wet environments, such as water tanks, aquariums, cold rooms, swimming pools, etc. The sensor is made of stainless steel, has a long service life and is sensitive to temperature changes.

The WTS01 type is an improved version of the DS18B20 sensor, which is equipped with an extended (approx. 150 cm) cable, an RJ9 connector, and is also compatible with the RL560 5-meter extension cable.

The range of the measured temperature is from -40℃ to 115℃, it works reliably in both high and low temperature conditions.

A cost-effective solution for sensing temperature and controlling Sonoff relays based on it. The sensor has an RJ9 plug that fits the Sonoff TH06R3 and TH20R3 sockets.

The sensor can be connected to the relay after de-energizing the relay. With the eWeLink app, you can set a set of temperature-related conditions that can turn the TH16 and TH20 relays on/off, and you can even control other relays in the network in this way, e.g. even an S26 smart outlet. The relay is also an ideal choice for controlling fans, electric heaters, radiators, humidifiers, dehumidifiers, air conditioners, irrigation systems and aquariums.

We recommend the Sonoff DS18B20 waterproof temperature sensor for the following products:

- for Sonoff TH Elite (THR316D, THR320D),
- For Sonoff TH Origin (THR316, THR320).
