Sometimes it’s the simple things in life that add up to make a very real difference, and in the case of smart door and window sensors that’s definitely the case.
When installed on your doors, windows, garage door or even cupboards, these tiny little sensors can bring a whole lot of peace of mind, convenience, and even safety.
So, let’s walk right in and delve into door and window sensors.
Easy to install and capable of being fitted to pretty much any household fixture that opens and shuts, door and window sensors use a simple magnetic mechanism to tell you whether something is open or closed.
When used as part of a smart home, door and window sensors can alert you on your phone when a door or window opens or closes, offering very real security benefits and potential peace of mind that goes far beyond break-ins or burglaries.
Known as reed switches, door and window sensors measure about 7cm long and feature two components with magnets inside.
The slightly larger component also accommodates a temperature sensor and Z-Wave technology. This part of the sensor is affixed to the door frame, while the smaller component is attached in a corresponding position to the door itself.
When the door opens and the magnets separate, the status of the contacts inside the switch change, indicating the door is open. When the door shuts the components come together and the sensor recognises the door is closed.
These sensors have the ability communicate with smart phones, and can send an alert when the status of the door changes.
Door sensors are powered by batteries which boast a lifespan of about two years.
The components of the door sensor feature screw holes, allowing them to be permanently affixed to the door and frame. They can also be attached using double-sided tape.
Due to their small size and simple operating method, door sensors can be fitted to any household fixture that opens and closes, meaning they can be installed on:
They also offer peace of mind, so you can quickly ascertain whether you left the front door ajar as you exited the home, or they can even tell you when your children arrive home from school.
For example, you might fit a door sensor to your bathroom door and set it, so the lights come on when the door opens.
Perhaps the greatest example of the convenience of door sensors is when you couple them with automation controls such as door openers and closers, and remote locking.
With these further features, you now not only understand what state your door or window is in but can also remotely do something about it.
Say, for example your skylight is open, and a storm warning is issued. With controls and sensors, you can shut the skylight using your mobile phone. Additional sensors and controls can even take this scenario a step further. Imagine your skylight is open, but a rain sensor becomes aware it’s started to rain.
With automation, the sensor can communicate with a control that now tells the skylight to shut, and you don’t even have to lift a finger.
Or, say your phone tells you the front door is open…with controls, you can command it to shut, and with remote locking you can instruct it to lock, even if you’re on the other side of town at work, or the other side of the world on holidays.
Better yet, you can actually program your home to take care of this automatically using a routine or scene and voice activation. Now, you simply tell your smart speaker you’re leaving for the day – the door automatically shuts, and locks firmly behind you.
These are just some of the examples of the convenience that automation can bring, and in each case, it starts with the simple but smart addition of a door or window sensor.
