Water leak detectors and thermo-hygrometers
Sensors that warn you about leaks, low temperatures or changes in humidity before they turn into damage. Some connect directly over Wi-Fi, others work through the SBS50 base station.

1 water leak detector
X-Sense SWS0A
The SWS0A spots water just 0.3 mm deep as well as drips from above, thanks to probes on both sides. At only 17 mm thick, it slips into tight spaces under appliances.

3 water leak detectors
X-Sense SWS51
The SWS51 sensors add leak detection to an X-Sense SBS50 base station, with three detectors in the pack. When water is found, both the sensor and the base sound and your phone gets a push alert.

3 sensors + 1 base station
X-Sense SWS54
The SWS54 kit contains everything you need to start watching for leaks: three sensors and a base station. Each IP66 sensor detects just 0.3 mm of water and alerts your phone.

3 water leak alarms
X-Sense SWS0B
The SWS0B detects leaks and warns you when the temperature drops below 4 °C, giving you time to act before pipes freeze. It connects straight to your Wi-Fi, with no base station needed.

3 thermo-hygrometers
X-Sense STH0A
The STH0A shows temperature, humidity and comfort level on a large 2.7-inch screen, and sends the data to your phone. With three sensors, you can follow several rooms at once.

4 sensors + 1 base station
X-Sense STH55
The STH55 kit gives you four temperature and humidity sensors plus a base station, ready to monitor your home around the clock. Readings are taken every 3 seconds and logged in the app.

X-Sense STH51
The STH51 sensors add precise temperature and humidity monitoring to an X-Sense SBS50 base station. Data is stored free of charge in the cloud and can be exported.
