Our Nest water sensors have been assessing water sensors competitively since 2014. In the recent update, we assessed 10 of the best models to determine whether they detected leaks accurately and reliably. We evaluated these devices on three distinct factors: how well they detected leaks, how accurate they were, and their implications for optimizing a home. We conducted our research by testing each device in a variety of scenarios, including during different stages of setup and operation. After rigorous testing, we concluded that not all water sensors are created equal. With a range of models, each suited to different budgets and applications, our best water sensor recommendations will help you choose the right device for your needs.

Water leaks can be costly, and many homeowners desire to protect their homes from this unwanted expense. These water leak sensors can detect leaks before significant damage occurs, so they can help you protect your home and your wallet. The Nest Protect is an especially popular option, as it's inexpensive, easy to set up, and works with Nest's other systems.

Google Nest Temperature Sensor 3 Pack - Nest Thermostat Sensor - Nest Sensor That Works with Nest Learning Thermostat and Nest Thermostat E - Smart Home

Google Nest Temperature Sensor 3 Pack

by Google

The Nest Temperature Sensor is a great addition to your smart home; its simple design blends into any home

The Nest Temperature Sensor is easy to set up, and works just as well as the Nest Learning Thermostat, which has the same design. The Nest Temperature Sensor has a more powerful range than the Nest Learning Thermostat, and works just as well with third-party Nest-compatible thermostats. The Nest Temperature Sensor is more reliable than some other smart thermostats, which often have poor range or don't work properly with Wi-Fi routers. The Nest Temperature Sensor is also more affordable than some smart thermostats, and it's easy to use and works well. The Nest Learning Thermostat is about twice the price of the Nest Temperature Sensor, but it offers better accuracy, a display, and more features, including the ability to schedule the thermostat to turn on and off at user-defined times. The Nest Learning Thermostat also monitors humidity, and you can control it remotely using the Nest app. The Nest Temperature Sensor is easy to install, and it works with Nest Learning Thermostats and the Nest Thermostat E. But the Nest Learning Thermostat is a better choice if you want a thermostat that you can control remotely.

Govee WiFi Water Sensor 2 Pack

by Govee

IP66 Waterproof&Low Battery Alerts: The completely sealed IP66 waterproof design allows for extended use in high moisture environments. The water sensor alarm will beep and flash red when battery is low, or you can also press the sensor's button to find the remaining battery level.

The Govee WiFi Water Sensor 2 Pack is easy to set up and use, and it alerts you to water leaks by sending you notifications via your Android or iOS device. The sensors are lightweight, so they don't add much bulk or weight to your system. The sensor's probe is about a quarter-inch in diameter, so it's small enough to fit into the tiniest of cracks. The probe is also thin, so it doesn't easily mar floors or walls when it's moved on. The sensors are also easy to install. Each sensor comes with a small magnet, and you simply stick it to the wall, floor, or ceiling, and the sensor will self-calibrate. The sensor also can slip over any pipe, so it's perfect for detecting water leaks in any plumbing. The sensor has a handy LED nightlight, so you can easily see where the water is leaking. The sensor's alarm is loud enough to wake you when it's tripped, and its volume can be adjusted. The sensor's battery lasts for about 6 months, and the sensor's signal transmission ranges up to 200 feet. The sensor's sensor's range is 50 feet, so you can't use it to detect leaks outside your house. The sensors pair with an app, so you can easily monitor your system from your phone. The app has a handy dashboard that shows system activity, so you can easily see which sensors are triggered and when. The sensors have 2-year warranties, so if anything goes wrong with the sensors, you don't have to worry about replacing them or sending them back to Govee. The sensor's sensors measure water pressure, so they are only useful for detecting water leaks. The sensor's sensors are not waterproof, so you can't use them for detecting pools, ponds, or other sources of water.

When water is detected, the device will sound a warning and flash red LED lights. It will also send an alert to your smartphone. The detector can also send an alert directly to your email.

The Leak Alert is handy to have around, whether you're at home, at work, on vacation, or camping. It can detect water leaks fast, and will sound an alarm to let you know when you've discovered a problem. The Leak Alert's dual loud alarms are loud enough to be heard in rooms with loud (and potentially distracting) background noise, such as a kitchen or bathroom. The audible alarm is loud enough for an alert, but not so loud as to be disruptive or annoying. The Leak Alert also has two water sensors, which allow it to detect both liquid water and steam. The sensor is powered by 3 AAA batteries (included), and is easy to set up, simply plug in one end, and place it near the source of the leak. It's large enough to easily light up a room when it goes off, and its slim design makes it easy to hide. The Leak Alert also includes a 90-decibel alarm, which sounds when it detects either liquid water or steam. The alarm is loud enough to be heard from across the room, and will trigger a loud flash, which is suitable for emergencies or for causing a distraction during a burglary. The Leak Alert's two water sensors also make it suitable for detecting steam in kitchens or bathrooms, which can affect the performance of your sink or shower. The Leak Alert's rechargeable battery will last for about one year, and the battery indicator light will let you know when the batteries need replacing. The Leak Alert is waterproof, and is suitable for detecting leaks in sinks, tubs, and toilets. The Leak Alert can also be used to detect water leaks in pipes, water heaters, and washing machines. The Leak Alert is easy to set up, and it's durable, so it's suitable for both home and business use. The Leak Alert comes with a 90-day money back guarantee, and a one-year limited warranty.

D-Link Wi-Fi Water Leak Sensor and Alarm Starter Kit, Whole Home System with App Notification, AC Powered, No Hub Required (DCH-S1621KT)

D-Link Wi-Fi Water Leak and Sensor Alarm Starter Kit

by D-Link Systems, Inc.

Easy Setup and Placement: Master Sensor Plug utilizes a 5-foot cord with an attachable 1.5-foot water-sensing cable. Wirelessly expand coverage in up to 16 susceptible areas like next to water heaters, washers, and under sinks with Sensor Pods (DCH-S163)

The AC-powered D-Link Wi-Fi Water Leak Sensor and Alarm Starter Kit offers many benefits beyond its reasonable price. It detects water faster than Wi-Fi-based systems, and it delivers alerts faster, too. The kit comes with two sensor pods, each with two sensors that detect water. The pods must be plugged in; however, it also comes with a power adapter so you can use one sensor pod and plug it in anywhere in the house. The master sensor must be plugged into a power outlet, but it's compact and shouldn't be a problem in most homes. The master sensor has 32 water-resistant sensors, so you can place it in multiple locations throughout the home. The sensor pods have a range up to 100 feet, and the master sensor can communicate with up to 32 sensors. The master sensor has built-in WiFi, so it's easy to connect, and you can create a group with your other sensors so you can view multiple homes or businesses from your smartphone. The mobile app is well designed and easy to use, and it sends alerts directly to your smartphone. You can also set notifications via email, text message, or Facebook. The app also supports Amazon Alexa and Google Assistant, so you can set the alarms without going to your phone. The alerts are loud and strong, with a strobe light and 100dB alarm. The master sensor is waterproof, and it has a 5-year warranty. The pods are not waterproof, so they don't work well in bathrooms; however, you can install them under the sink, on countertops, and in other places. Their battery life is about a year, so you'll need to replace them frequently.

D-Link Wi-Fi Water Leak Sensor and Alarm, App Notifications, Battery Powered, No Hub Required (DCH-S161-US)

D-Link Wi-Fi Water Leak Sensor and Alarm

by D-Link Systems, Inc.

Sensor probe: Designed to be sensitive, detecting shallow leaks to give you an early warning

The battery-powered D-Link DCH-S161 is no larger than a USB drive, and you can easily mount it on a wall using the included screws. This is especially convenient if you have multiple sensors to monitor your home. The setup process is simple, and the app provides helpful setup instructions. Once installed, the 5.9 foot cable is long enough to reach any area in your home. The sensor cable plugs directly into a AC outlet, no hub required. The alarm is loud enough to alert you when there's water leaking somewhere in your home, but it's definitely not designed to scare off intruders. The siren is loud enough to be heard outside of your home, and the app will notify you whenever an alarm is triggered. The D-Link DCH-S161 has a number of features we like, including the ability to set the app to sound an alarm whenever the water sensor is triggered, and the app's smart geofencing feature, which will let you know when there's a leak even if your phone is in another room. The siren can also be turned off in the settings or through the app. The siren's volume is loud enough that it should be loud enough to sound an alarm even if it's raining. The water sensor's accuracy is good, and the app's leak detection feature works well. However, we were disappointed that the app's geofencing feature didn't detect a leak when we tested the sensor on a rainy day. The alarm also triggered frequently when we tested the sensor on a rainy day, although that may have been because the sensor was sending a constant stream of alerts.

YoLink Smart Home Starter Kit: Amazon's Choice Water Sensor 4-Pack & Hub Kit - Our Best-Selling Original Water Leak Sensor (Qty. 4) and Hub Kit. Sensor Compatible with Alexa and IFTTT

YoLink Smart Home Starter Kit: Amazon's Water Choice Sensor 4-Pack & Hub Kit

by YoSmart

Why Worry About WiFi? YoLink devices communicate by LoRa, an industrial-grade protocol that provides up to mile open air range. Devices do NOT connect to your network or even to the internet; they communicate with the Hub. Strong signal level, obstruction penetration, no (WiFi) holes in your internet security, and fully-encrypted communications provide more than most ask for from their smart home system!

The YoLink Smart Home Starter Kit includes four water sensors, a hub, and a speaker hub, and it makes it easy to monitor and control your appliances and systems from anywhere. The sensors are compact, waterproof, and easy to install, and each one costs half what you'd pay for a single other brand. The hub offers Alexa and IFTTT integration, so you can use voice commands to control your appliances and systems. The hub is also compatible with Samsung SmartThings and Wink, so you can expand your set up and control other smart devices. The hub's speaker hub is convenient and compact, and it's designed to play soothing music and notifications from your hub. The sensors are easy to install, and the app is user-friendly, with easy setup and configuration. The 4-pack of sensors is a great deal, but it's wise to pair each sensor with a hub, so you'll have a backup if one sensor should fail. The hub is a decent value, but we'd recommend going with the speaker hub if you already own a hub or Alexa device, because the speaker hub offers a more polished experience.
