Respond to water intrusion before it becomes damage with a leak sensor kit designed for direct, connected alerting. The D-Link Wi Fi Water Leak Sensor Kit, MPN SW-A11KT, combines a plug-in master unit with a battery-powered sensor so you can monitor two locations immediately. The included 1.5 ft detection cable helps place sensing where leaks are most likely to appear, while Wi-Fi connectivity sends notifications to your phone without requiring a separate hub. For local awareness, the system adds a built-in 100 dB siren and LED strobe, giving occupants a clear audible and visual warning when water is detected. That matters in spaces where a phone alert may not be enough, such as basements, utility rooms, laundry areas, or equipment closets. The kit is also built for growth. It supports expansion to as many as 17 sensors total, allowing a single deployment to cover multiple risk points across a home or small business. For buyers comparing low-cost leak alarms to a connected system, this model offers a stronger balance of immediate alerting, multi-location coverage, and room to scale as the property changes.
