IoT-ready smart lighting manager ICs feature multi-sensor support

Ams's new Smart lighting manager ICs support network-commanded dimming, daylighting and other basic smart lighting functions as well as an autonomous mode which only relies on a local or remote host for configuration and exception handling. Unlike most of their counterparts, they have highly-accurate built-in light sensors which enable precise daylighting, lumen maintenance, and in the case of the AS7221, color tuning. In addition, the same sub-$10 solution that drives the lighting system can also serve as a low-cost platform for many other Smart Building services. Read More...
