Looking to give your home a tech-savvy, 21st-century makeover? You may have the heating, power and lighting nailed down, but in this section you'll find a range of smart home alarms and sensors, all of which will give your home an edge when it comes down to security and safety. Whether you want to detect intruders or perhaps you live in a home at risk of flooding, there's a sensor or alarm to match. Take a look through our range of alarms and sensors from brands like Devolo, D-Link and Hive below.

Making your home safer and more secure is easy with the smart home alarms and sensors listed on this page. They'll defend your home from intruders and environmental threats, giving you warnings and the time to take action.

We stock products such as motion sensors for doors, windows and rooms; smoke, water, carbon monoxide and humidity sensors; and mounts to place them. Then there are alarms which either emit noise or notify you via a smartphone app, letting you keep on top of any issues that arise remotely.

All of the major smart home brands can be found in our range, and if your order comes to £49.99 or over we'll throw in free delivery. What's more, if you find what you want elsewhere for less, we'll match the price under our price match promise.
