If you want to know more about water sensors and what you need to know when purchasing one, here are answers to some common questions you may have:


What Is a Water Sensor?

In its most common design style and form, a water sensor is a small device that, when lying flat, will alert the user in some way when water comes into contact with or submerges the device. These devices come in various shapes and models, and they may be battery-powered, require the use of an outlet, or operate from either of those sources. Whatever sensor model you have, it will come in handy the next time you have a leak of some sort in the area where you place it.


What Is the Difference Between a Smart Water Sensor and a Standard Unit?

Unlike a “regular” water sensor, a smart sensor has Wi-Fi connectivity and thus the ability to collect to a compatible hub and be controlled remotely via your smartphone. You will be able to connect your smart sensor to your device via an application specifically designed for this purpose, providing you with genuine peace of mind. While a traditional water sensor will typically make a loud noise to alert you to a potential issue, this only works if you are home to hear the alarm. Here’s the bottom line: a smart sensor can alert you to a water emergency regardless of your location.


Where Should a Water Sensor Be Placed?

You should place your water sensor somewhere close to appliances that operate using water or in another area of concern and risk. For instance, if you have a leaky dishwasher that acts up from time to time, you will want to put a sensor close to your dishwasher. You can also put sensors near your HVAC system’s components or under sinks near the pipes. Water sensors are typically small enough to fit most places you would consider putting them. Remember to check whether your sensor requires an outlet when you are ready to make a purchase with a specific trouble spot in mind.


Where Can I Buy Water Sensors?

You can purchase water sensors from various retailers in your area, or you can take advantage of the strong selection and wealth of product information available online at sites such as Amazon.
