Honeywell Lyric Leak and Freeze Detector

D-Link Wi-Fi Water Sensor

Everspring Z-Wave Wireless Flood Detector

Aeon Labs Aeotec Water Sensor

SmartThings Water Leak Sensor

FortrezZ Water and Temperature Sensor

Fibaro Flood Sensor

All flood sensors work the same way. They have two or more leads that, when they contact water, detect higher conductivity. Then they set off an alarm and/or send your phone an alert. What distinguishes each device from its competitors is the extra features.

Honeywell Lyric Leak and Freeze Detector

D-Link Wi-Fi Water Sensor

Everspring Z-Wave Wireless Flood Detector

Aeon Labs Aeotec Water Sensor

SmartThings Water Leak Sensor

FortrezZ Water and Temperature Sensor

Fibaro Flood Sensor

The Honeywell Lyric Leak and Freeze Detector is one of the most expensive flood detectors out there. At $80, it measures temperature and humidity, works using Wi-Fi rather than a smart-home hub, features a loud alarm, and has a cable of twisted leads that extend the sensing range of the device considerably. Sadly, however, the Honeywell isn't waterproof and doesn't work with many other smart-home gadgets.

The D-Link Wi-Fi Water Sensor, at $60, doesn't rely on a smart-home hub like most of its competitors do. It also features a cable of twisted leads like the Honeywell Lyric. Its real strengths, though, come from not relying on batteries and working with IFTTT for cool smart-home integrations.

FortrezZ Water and Temperature Sensor

Fibaro Flood Sensor

The Everspring Z-Wave Wireless Flood Detector costs $40 and features a long, wired probe. Unlike the D-Link or Honeywell, this wire only has probes at its end, so it doesn't sense floods along its length.

FortrezZ Water and Temperature Sensor

Fibaro Flood Sensor

The Aeon Labs Aeotec Water Sensor is $35, but is otherwise almost identical to the Everspring. It's perfect for measuring water levels in a sump pump, but it won't work well under a sink or for monitoring larger areas.

Fibaro Flood Sensor

The SmartThings Water Leak Sensor is an affordable $40, but it has very few extra features to speak of. It works effectively, especially if you already use the SmartThings platform.
