Meet Noah™, the flexible water leak detection sensor from Kairos. Designed to constantly monitor the presence of water where you don’t want it. This tiny sensor offers a powerful solution which can be customised to meet your requirements.

Simply attach the sensor to the accompanying membrane to benefit from a truly flexible water leak detection sensor. The membrane can then be placed wherever you want to monitor and is available in a variety of sizes. Any detection of water will raise an automated alert to your selected device.

Example use cases for the Noah™ flexible water leak detection sensor include:

  • Water Heaters
  • HVAC systems
  • Washing Machines
  • Refrigerators
  • Server Rooms
  • Dishwashers
  • Boiler Rooms
  • Commercial & Residential properties
  • High rise buildings
  • Wrap around pipes
  • Substrate flooring

& much more!

Unlike rope or spot leak sensors which need to be placed in the right area. This flexible solution is designed for reuse, durability and longevity. The flexible membrane can be supplied in various sizes to meet your needs, and can be configured to detect leaks based on zones, helping you to identify any problems as/when they arise.

The membrane can be purchased in a strip format or as a mat. Alternate sizes are available, talk to us today about your requirements.

Utilising LoRaWAN® technology, this flexible water leak detection sensor will transmit recorded data through a LoRaWAN® gateway. Data is then passed through to your chosen visualisation platform via a LoRaWAN® Network Server.
