We are the first patented leak sensor solution using flexible printed membranes with LoRaWAN technology. Our sensors are designed to detect leaks in water pipes, gas lines, common appliances, and other infrastructure. With our smart sensors installed, property owners can save money by detecting leaks and mitigating risks before major water damage occurs.







  • No need to replace them after use, membranes are 100% reusable 
  • Understand the severity of a leak
  • Coverage for any area or appliance you want to monitor
  • Easily install in under 3 minutes!


1x12 Membrane

  • Common types of leaks found in the home include worn toilet flappers, dripping faucets, and other leaking valves. All are easily correctable.
  • Ten percent of leaks waste 90 gallons or more per day.
  • Most common leaks can be eliminated after retrofitting a unit with new Kairos labeled fixtures and other high-efficiency appliances.



9x18 Membrane

  • The main cause of water leaking from your HVAC system is an issue with the drain pan
  • Broken condensate pans are a very common source of issues



20x20 Membrane

  • Average leaks are equivalent to 1,200 loads in the dishwasher
  • Running the dishwasher only when it's full can eliminate one load of dishes per week and save the average family nearly 320 gallons of water annually.
  • Letting your faucet run for five minutes while washing dishes can waste 10 gallons of water and uses enough energy to power a 60-watt light bulb for 18 hours.



6x30 Membrane

  • 75% of Water Heaters Fail within 12 Years
  • 250 Gallons of Water Can Be Lost in a Single Day from a 1/8-Inch Crack in a Pipe
  • The Insurance Institute for Business & Home Safety puts water heater failure in the top five causes of water damage



9x18 Membrane

  • A leaky faucet that drips at the rate of one drip per second can waste more than 3,000 gallons per year. That's the amount of water needed to take more than 180 showers!
  • Leaky faucets can be fixed by checking faucet washers and gaskets for wear and replacing them if necessary.



20x30 Membrane

  • Ice maker malfunctions are a major source of issues for refrigerators
  • Water filter problems often result in similar issues
  • If the defrost drain is clogged, water will back up into the freezer and down into the fridge. Eventually, it will pool on your floor.



Tape Membrane

  • Roofing leaks can cause catastrophic damage to properties if not detected over time.
  • Leaks during construction are common but add time to the project.

Frequently Asked Questions

What is a membrane?

Membranes are our patented technology. Think of it as a sensor in the shape of a strip or sheet which can detect liquids anywhere on its surface, rather than traditional sensors, which can only detect liquid at a single point. this drastically increases our ability to detect small leaks, such as a single drop, across a large area like a water heater, dishwasher, or washing machine. 

Do I need to replace the membranes?

Nope! Our membranes are 100% reusable.

Do I need wiring to install a membrane?

None! You simply connect the end of the membrane to a sensor and it's good to go!

Can I place items on top of the membranes?

Yep! It can go anywhere you want to detect water, including the bottom of appliances.

How does the toilet strip not alarm when it gets wet from water on the floor from the tub/shower?

Our sensors are placed on the back of the toilet and the 1x12 membrane uses an adhesive to go below it.


After having our Kairos equipment installed, we have seen the benefit far outweigh the upfront cost. We have seen it prevent numerous major HVAC leaks from an upstairs to a downstairs unit allowing us to get in and make the necessary repairs before flooding to the downstairs unit, which on average would cost us $3000 depending on the severity of the leak. The team has been highly professional and fun to work with. Not only are we getting a great product, but we are getting educated in the process of how it can save our bottom line in the long run.

    As many apartment communities in Florida experience, the threat of organic growth is much higher due to the humidity. Additionally, a single leak in one unit had the potential to damage the units next to it and the units below. In one particular community, a proactive inspection of the property led to the discovery of a significant water leak.

    In most leak detection systems, gateways run on networks with fairly limited ranges. This is why it is standard to place one on each floor to ensure no detections of leaks go unnoticed. Since the K1 Gateway runs on a LorAWAN network (Wide Area Network), a leak on the 16th floor was detected after installing only 2 gateways. Rather than having to install 16 devices, the leak was identified at the very beginning of the installation process and addressed immediately.
