There are many reasons to protect your home from water damage, whether it's frozen pipes, a busted water heater, or a leaking washing machine. Even if you're not at home, a smart water detector can detect leaks and send alerts to your phone.

Water Leak Sensor

The lists below are the recommendation of water leak sensors that may help you to buy one;

  1. Flo by Moen Smart Water Leak Detector

The Smart Water Leak Detector by Flo by Moen sends near-instantaneous alerts to our iOS and Android smartphones, as well as via email. When the sensor detects a leak, it emits an alarm sound and illuminates red, as well as sends timely alerts in a couple of seconds.

The sensor also monitors the temperature and humidity levels in your home, which might aid with moisture management.

The Flo by Moen detector's compact design makes it easy to install in tight spaces. The sensor may also be readily moved under washing machines and other difficult-to-reach areas where moisture can accumulate.

Overall, the Flo by Moen Smart Water Leak Detector is the smartest leak detector on the market, providing real-time warnings when a leak occurs. This leak sensor is a smart investment for any homeowner because of its simple setup, rapid installation, and ease of use.

  1. Wasserstein Wi-Fi Water Leak Sensor

Wasserstein Wi-Fi Water Leak Sensor is the best value option for various reasons. Despite not being the fastest at sending warnings, it managed to transmit notifications in within 20 seconds over both Wi-Fi and cellular connection, which is spot on.

The setup procedure is as simple as it gets. The Wasserstein App is accessible by a scannable QR code in the instruction booklet, and it takes less than a minute to follow the steps and have the leak detector up and running.

The probe that comes with Wasserstein's leak detector is a useful addition if you wish to put the sensor underneath or under a washing machine or dishwasher. It also has a wall anchor, allowing you to hang the bigger section of the leak detector nearby and place the probe where potential leaks may occur.

  1. Phyn Plus

Phyn Plus is a smart water sensor that can be used alone or in conjunction with the more expensive gadget. You'll gain the maximum advantage from Phyn's sensor if you also own the Phyn Plus, but using the sensor alone will give you plenty of warning that you should manually shut off your water supply before you incur serious water damage, just like the Flo by Moen Smart Water Detector.

  1. D-Link DCH-S161

The D-Link DCH-S161 is an excellent choice because its loud, 80-decibel (dB) alarm can be heard over a long distance in a home. It also includes Google Assistant and IFTTT (If This Then That) connectivity, allowing you to connect the sensor to other smart devices and ensure that notifications are received.

The D-Link is one of the few devices we examined that allows you to silence alerts both on the device and in the app. Although the accompanying 6-foot sensor line is longer than the Flo's, we found that it doesn't react as rapidly to water and communication concerns, and it lacks a temperature sensor.

  1. Ring Alarm Flood and Flood Sensor

If you have a Ring alarm system, the Ring Flood Sensor is the ideal leak detector to pair with it. Because the water sensor requires the use of an alarm system, we only recommend it for households with existing Ring systems.

The little circular device is flat enough to fit under sinks, refrigerators, toilets, and other leak-prone places. Because it does not include an extension probe like some other leak detectors, be sure Ring's design suits your planned usage location before purchasing.

It works perfectly after it's installed, giving timely smart warnings to your phone or tablet whenever it comes into contact with water. It can also notify you when the temperature lowers, alerting you to the possibility of frozen pipes. There are no Alexa connections for Ring's flood sensor right now—only push notifications. The sensor is controlled by the Ring app, which requires two-factor authentication.

New Trend Water Leak Sensor 

Battery-Free Leak Sensor Taps Nordic's BLE SoC

AquaSensing, a Canadian technology startup, has invented a battery-free, self-powered leak detecting device. "Leak Sensor 1.0" employs Nordic Semiconductor's nRF52832 Bluetooth 5.2/Bluetooth Low Energy (Bluetooth LE) multiprotocol System-on-Chip, as well as a proprietary sensor that serves as both a power source and a sensor for detecting water leaks (SoC).

The nRF52832 SoC-based Bluetooth LE radio in Leak Sensor 1.0 is powered by any fluid incursion and communicates wirelessly to the user's Bluetooth 4.0 (and later) smartphone. The user can then receive active leak alerts via an app or a text/email message. Users can also control and configure the Leak Sensor 1.0 device through the companion app, pause or mark notifications as resolved, and share leak details with third parties to act on the alert.

The nRF52832 SoC supports Bluetooth 5, featuring 2x on-air raw data speed (2Mbps), 8x broadcasting, advertising extensions that extend the advertising packet payload size to 251 bytes, and a channel coexistence algorithm that has been improved.

According to the business, the Leak Sensor 1.0's tiny form factor makes it simple to install at any remote area. Because of the inert materials employed, Leak Sensor 1.0 can operate for more than 20 years, allowing it to be safely placed behind walls and in difficult-to-reach regions during building and manufacture. The system may be scaled to cover enormous areas of complex structures.

The Nordic nRF52832 multiprotocol SoC combines a 64MHz, 32-bit Arm Cortex M4 processor with floating point unit (FPU) with a 2.4GHz multiprotocol radio (supporting Bluetooth 5.2, Bluetooth mesh, ANT, NFC, and 2.4GHz proprietary RF protocol software) with 4dBm output power and -96dBm RX sensitivity for a link budget of 100 dBm, as well as 256/512k

Water Leak Sensor



The cost of smart water sensors can range from $50 to over $500. The more economical devices are simply leak detectors that communicate via Bluetooth or as part of a home automation system and don't have a Wi-Fi radio. The cost of smart water sensors can range from $50 to over $500. The more economical devices are simply leak detectors that communicate via Bluetooth or as part of a home automation system and don't have a Wi-Fi radio.

Environmental monitoring, extension cables, sirens, and LED indicators, as well as other connectivity options like voice control and IFTTT support, will cost extra. In-line systems, which monitor your entire home and cut off your water if they detect a significant problem, are at the top of the market. Remember that, in addition to a high price, in-line systems will require professional installation, which will add $200 or more to the entire cost.
