A gate alarm can notify you when you are about to have visitors, have an unwanted visitor, or have youngsters venturing beyond the confines of your yard. Many people assume that having a gate alarm is costly and/or difficult because of remoteness of the gate. Home automation solves this problem with battery-operated wireless sensors.
Door Sensors Work As Gate Sensors
Most door sensors are composed of two halves. When the two halves are separated, an RF signal is sent to the attached controller, triggering whatever event is programmed to happen. The two sensor halves don’t have to be in contact, only close enough to each other (typically ½ inch) to indicate a closed condition.
Most sensors install with either two-sided adhesive tape or mounting screws, allowing you to install them on both metal and wood surfaces. Sensors are small, making them easier to hide. Because sensors are magnetically activated, they can also be painted (to blend in) or coated with plastic (to waterproof).
Compatible With Multiple Wireless Home Automation Technologies
Door sensors are common in the home automation industry and can be found in Z-Wave, INSTEON, and ZigBee platforms. Using a compatible controller, the gate sensor can trigger any device or group of devices, such as lights or alarms, or initiate a home automation scene through a scene controller or computer interface. Using an automation gateway, the gate alarm can also notify you remotely via your home Internet connection.
