What do you think of when you think of “smart” technology? Smart phones, smart appliances, smart watches, smart homes, and smart TVs might be just a few that come to mind. However, the word smart is now getting smarter. Consumers are constantly looking for that next great feature to make their technology more advanced. One feature that a lot of this smart technology is trying to adopt is presence detection, meaning if a TV is on, but can detect that a user is not within the viewing area for a certain amount of time it would turn off, pause the show, go to standby, etc. Similarly with speakers, it can go to a standby mode which allows for higher efficiency. This can be done with the TAS5825M from Texas Instruments using ultrasound technology, which can be used to map the acoustics of an environment and determine how sound reflects off the surroundings to project audio accordingly.
