Water Sensor

How Water Sensor Helps Automate Your Home

A leaky pipe or backed-up toilet can cause significant damage to your home, not to mention the resultant costly repair bills. A water sensor can help you detect leaks and get them fixed before they do any substantial harm. When placed in areas like laundry rooms, near water heaters, or under sinks, they can sound an alarm whenever it detects water and automatically shut off the water supply to prevent further damage.

In addition, many smart home plumbing systems offer a water sensor as part of their home automation packages. These sensors work in conjunction with other smart devices to create a fully automated home that you can monitor remotely via a mobile app.

How water sensor works

Water sensors are usually battery-operated and connected to your Wi-Fi network. Once connected to your home network, they can be programmed to send alerts via email or text message to the mobile device of your choice. For example, if there is high humidity, the sensor will alert your hub.

You’ll know right away if your basement is flooding or if there’s a leak under the sink.

If a pipe bursts, the water sensor will send you a notification. You may then choose to shut off your water mains or call for professional help before the problem escalates. Some advanced systems will even integrate with other devices like smart locks, lights, and thermostats. For instance, once it detects a leak, the system may lock all doors and windows, turn off the air conditioning system and turn on all lights.

Types of water sensors

Many water sensors detect moisture, humidity, or temperature in your home. They monitor a basement for leaks or floods, a water heater and its pipes, outdoor landscaping, and more. Here’s more about the types of water sensors you can use.

Flood and leak detectors

Flood and Leak Detectors

These devices suit basements, garages, laundry rooms, and near sinks to monitor moisture. Some have internal batteries that send alerts even if the power goes out. Some water sensors have temperature sensors as well. The more expensive models offer more sensors and options for receiving alerts when it detects water.

Water heater leak detectors

Water heaters have a limited lifespan of 10-15 years. Manufacturers sell leak detectors that you can attach to your water heater to sense leaks early before it becomes a more significant problem. These devices usually mount on the floor near your hot-water tank with a small probe that sticks into the drip pan underneath the tank.

If there’s any moisture in the pan, you’ll receive an alert via text or email long before you’d notice anything else. Look for models that allow you to add additional sensors to monitor other potential leak zones.

Float sensors

Float Sensors

Float sensors detect when water levels rise above a specified point. The float sensor is placed within the tank and floats up and down with the water level. The float sensor can be an indicator or a control mechanism that automatically shuts off the water supply when it senses a high water level.

Pressure sensors

Pressure sensors detect leaks and drip within your home or business. When it senses pressure on a specific area, the sensor will trigger an alarm or shut off the valve to prevent further damage.

Capacitive Sensors

Capacitive Sensors

These sensors detect changes in capacitance. The sensor consists of conductive plates in a dielectric material. When water touches the plates, it changes the capacitance, and the sensor can detect the variation.

Leak detector

Leak Detector

A leak detector is a tiny device that you can place under sinks, next to washing machines and other areas where leaks are likely to occur.

Benefits of using a water sensor

A water sensor is a device that attaches to your pipes, drains, or other areas where flooding might occur. It will immediately alert you if any leaks are detected so you can quickly call a professional and fix the problem before it gets out of hand. It can save your home and belongings from the hazards of water damage.

A sensor will detect leaks early on so you can take action before there’s too much damage. A water sensor helps prevent mold growth, which may harm your health and your building structure. In addition, it helps keep your family safe from potential hazards such as electrical shocks or even death due to electrocution. A water sensor is essential if there’s an older adult living with you at home and may not notice these defects due to old age.


Automation is the obvious way to make your home smarter. One handy system is setting up a water sensor in your home. The project can be completely automated, so you’ll never have to worry about whether or not your home will flood. Instead, you’ll know when it does and can act accordingly regardless of where you are anytime.
