What comes to mind when you think about smart home security systems? You likely gravitate toward motion sensors, security cameras, remote thermostats and more, but have you ever wondered about the components in these devices?
For instance, tilt sensors ensure your garage and gates stay locked, whether you’re at home or away. But how do they work? What do you need to know about these mechanisms, and why should you invest in them in the first place? Find out more about the technology here.
What is a tilt sensor?
As the name implies, tilt sensors enable users to detect orientation or inclination. Compared to other sensors, they’re small, affordable, easy to use and, when used properly, don’t wear out. Additionally, some people refer to them as mercury switches, tilt switches, or rolling ball sensors.
Typically, the components include a cylindrical cavity and a conductor inside to pass along electricity. When an item lines up straight, the conductor sits in the cavity and allows electricity to pass throughout the sensor. When a tilt occurs, the conductor moves out of the cavity, cutting off the electrical signal.
More than a detector
Garage door controllers use tilt sensors to monitor whether a garage door is open or closed. When connected to your smart home network, you can control your doors from a smartphone or mobile device and receive home security alerts when someone leaves the door open.
