General Description
When water is present on a KAIROS’ Leak Sensing Membrane attached to a NOAH Multifunction Leak Sensor, an alarm message is sent to any K1 Gateways within range. When the attached membrane has no water present on it, a message is sent to remove the alarm. NOAH operates in LoRaWAN™ Class A mode.
NOAH uses LoRa radio technology for long range, low power, high penetration, low data rate applications. The unit transmits to the KAIROS web and mobile dashboard, which can be set-up to send alerts to any number of users (e.g. building engineers, front desks, residents, owners, security, etc) who should be alerted to the presence of water wherever the sensor is located. The low power characteristics of this new technology allow for up to ten years of battery-powered monitoring. NOAH’s small form-factor make it easy to be installed discretely and out of the way.
Applications
NOAH Leak Detectors is suitable for monitoring water intrusions in leak prone areas. KAIROS Leak Sensing Membranes are available in a variety of formats to suit any application. It is possible to print and cut custom membranes when necessary. A few recommended locations include:
- Water heaters
- Sinks
- HVAC/PTAC systems
- Skylights, Roof Vents
- Toilet bases
- Ice Machines
- Dishwashers
- Refrigerators
- Clothes Washers
