🌡️ Waterproof Temperature Sensor for Versatile Use

Sonoff WTS01 is a waterproof temperature sensor that can be connected to Sonoff TH10 and TH16, as well as to devices like the FIBARO Implant, Shelly Uni, and similar. Its waterproof feature makes it suitable for use in humid environments. The sensor is made from durable materials and offers excellent longevity.

The measurement range of the SONOFF WTS01 sensor is from -55°C to 125°C, making it reliable at both low and high temperatures.

The sensor features a 4-pin jack, allowing easy connection to Sonoff products. The package also includes an adapter to convert from the 4-pin jack to an RJ9 connector.

If you want to connect this sensor to devices like the FIBARO Implant, Shelly UNI, and others, you can cut off the jack and connect the sensor using wires. For the FIBARO Implant, the connections are as follows: connect the blue wire from the implant to the black wire from the sensor, the white wire from the implant to the yellow wire from the sensor, and the brown wire from the implant to the red wire from the sensor.

📝 Note: The length of the sensor from one end to the other is approximately 1 meter.
