What is a Door Sensor?
The main function of door sensors probably comes as no great surprise: they detect doors opening or closing. So far, so simple. But that’s really just the start.
In this article we’re going to investigate every aspect of these quietly clever little devices – how they work, what they can do, how much they cost and what happens when you start connecting them with other devices…
How do door sensors work?
Door sensors connect to your WiFi via a hub in your home. (This is a little device that you plug into your broadband router). Then, when your door’s opened or closed, you get a notification on your phone.
They come in two parts: one contains a ‘reed sensor’ and the other contains a magnet. When they’re close to each other, a current flows between them. When they’re separated the current is cut. And that’s when you get a notification.
How do you install door sensors?
First you do the internet bit: open your app and connect your sensor to the hub. (Don’t worry: it’s very easy and your app will guide you every step.)
Then you do the practical bit: stick one part of the smart door sensor on the door and the other part on the door frame.
Ours come with adhesive strips which are really secure, so there’s no need to dig out the tools.
What are the benefits of wireless door sensors?
Doorways and downstairs windows are your home’s most vulnerable points. A door sensor is a great way of knowing the moment they’re tampered with, so they’re very useful from a security point of view.
They’re great for peace of mind too. If you think you’ve left a window open just open your app and check. Then get a neighbour to pop round to shut it if you need to.
And when you’re on holiday, it’s just nice to know that as long as you don’t get a notification, there’s no need to worry.
How do sensors connect with other smart devices?
At Hive, we have a whole ecosystem of smart products that work together to get your home working around you. The mighty little sensor has a big role to play in that. Here are a few clever combinations, with door sensors at their core:
Door sensors and smart cameras
Connect your door sensor to your indoor camera. Then when you leave home, your sensor can turn the camera on automatically the moment you close the front door.
Door sensors and smart lights
Connect the sensor on your front door to a smart light in your hallway. When you get home on a dark evening, the light will welcome you back the moment you open the door.
Door sensors and smart alarms
If you already have a Hive door sensor then you can take the security side of things even further, with HomeShield, our smart alarm system. Subscribe to HomeShield, add the devices you want (like our brand-new siren and keypad) and use your door sensors to trigger your alarm.
HomeShield is pretty ground-breaking technology that gives you complete control of every aspect of your home security. And it all starts with your sensors.
