Detecting water accumulation at defined horizontal surfaces or positions such as below bath tubs or basements.


For the detection of water accumulation at defined horizontal surfaces or positions (e.g. below pipes, fittings and in the area of washing machines, below bath tubs or dishwashers, in utility rooms or basements). Suitable for water.


WaterSensor eco is equipped with fibre disks that work as a sensor; it does not require an additional power supply. In the case of a leak, the fibre disks expand and generate the required power to send the event message to the Mobius gateway. The event message is sent when the fibre disks expand or shrink.

  • Detail

Features, Benefits & Functions

  • Wireless Leak Detector  
  • Liquid sensing cable technology  
  • Sensing cable options: 3, 6 or 10 feet (`1, 2 and 3 m)  
  • Leak detection response- time to transmit is less than 8 seconds  
  • Works in dark places  
  • 64 second heartbeat
  • Red LED indicator  
  • Battery powered with 3V lithium coin cell  
  • Reliable radio reception range of 24 m (80 ft) - commercial office spaces (typical), up to 100 m (330 ft) line of sight  
  • Push button for linking and clearing sensors leak state  
  • Mounts with single screw or double sided tape (not included)  
  • Available at 902MHz and 868 MHz


The detector broadcasts a heart beat every 64 seconds to confirm the link with the sensor and to indicate that no water leaks have been detected. If there is water detected, a transmission is issued within 8 seconds.  The push button can be used to clear the sensors latched leak state.  The slim profile of the sensor allows it to be mounted unobtrusively behind equipment. The detector can be mounted on a wall or other vertical surface near the floor using a single screw or double sided tape (not included).
