The D-Link water sensor is intelligently designed and has all the important advantages to making it an effective flood detector.
The only real weakness of D-Link is that it is based on being connected, which means that the power outages are the Achilles heel.
The D-Link water sensor is,maybe,one of the best flood sensors on the market. If you are thinking of buying such a device, this should be the first option in your list, especially if you do not yet use a Smart-Home hub.
The design behind the leak detectors is really very cool: essentially, most sensors have two or three metal probes that, when they come into contact with water, detect greater conductivity and set an alarm. It’s an elegant solution to the old flood problem.
D-Link Wi-Fi water sensor
But D-Link adopts an even more creative approach. Instead of using probes, the D-Link’s Wi-Fi water sensor uses a cable with long wires and interwoven embedded in it. You can run the cable along the edge of the basement, say, and if the water touches everywhere, twisted wires detect greater conductivity and set an alarm.
The greatest force of D-Link is also a weakness, however. It doesn’t need batteries, but if the power goes off at the same time as a flood, it can’t do anything. Of course, battery-dependent devices will not be able to communicate with their hubs if power is off, but it can sound at least an audible alarm. It is not so with D-link.

While the D-link does not have the same ability to measure the temperature and humidity of the most expensive units, it is compensated by integrating with IFTTT. This allows users to creatively connect the D-Link sensor to their smart LEDs, phone applications or even an intelligent switch with an alarm. This is a great approach to allow users interested in troubleshooting DIY the freedom to link the D-link into a much larger system than integrated gadgets.
If you are looking for a flood sensor connected this season, the D-Link device is one of the best on the market.
