Abstract
An arrangement includes a plurality of microsystems and a controller. Each of the plurality of wireless microsystems is operable to measure at least one parameter of a space, and to transmit the at least one parameter wirelessly. The controller is operably coupled to receive the information corresponding to the at least one parameter directly or indirectly. The controller is operable to cause a change in a lighting control level based at least in part on the information. The wireless microsystems may suitably measure light levels and/or occupancy regarding the space.
