What makes smart buildings smart, and how wireless power can help

07 August 2018

Smart buildings are smart because they contain a lot of sensors. These sensors collect lots of data and this data is then analyzed to optimize comfort, power consumption and so forth.

Within reason, it’s good to have lots of sensors. With lots of sensors, you can get very granular data about the building.

The sensors typically report their data through some wireless communication link: WiFi, 4G, Bluetooth, Zigbee, etc.

But how do the sensors get power? Today, they are either battery powered or wired. Battery powered sensors need to be consistently serviced so that the battery does not run out. If you have many sensors in the building, you’ll have a small army of battery changers. If the sensors are wired, the act of wiring them is expensive and time-consuming. Now that the sensors are in place, re-wiring them with every move, add or change is also a pain.

This is where wireless power can help. If the sensors were able to receive power without wires, many benefits would emerge. No battery changes would be required. No expensive wiring jobs.  If the building needed more frequent sensor reports, the sensor designer would not have to worry about a very limited battery power budget.

Changes would also be easy, and adding sensors to optimize the building would also not be as expensive as if they had to be wired.

In short, sensors make buildings smart. Wireless power makes sensors better and buildings smarter.
