With Ambient Sensing, groups of Zigbee devices—like smart lights—can work together to detect motion in a given area.

Ambient Sensing for Zigbee lights allows zone-based lighting setups with just a firmware update and no additional hardware. Philips Hue products may support Ambient Sensing, requiring at least three lights.

The Connectivity Standards Alliance (CSA) has introduced a feature named “Ambient Sensing” in a recent video announcement. There aren’t many details on this new feature, but from the video we’re assuming it utilizes Zigbee technology to detect presence within a room by analyzing interference in connection signals.
