We consider networked control of luminaires to adapt illumination in an indoor environment to occupancy and daylight based on distributed light-harvesting wireless sensing modules. Each light-harvesting wireless sensing module consists of an occupancy sensor, a light sensor, a wireless radio, a microcontroller unit, and a photovoltaic cell. The occupancy sensor and light sensor, respectively, determine...
A light-harvesting wireless sensing system is proposed for indoor lighting control. A low-power light sensor and motion sensor operates on a photovoltaic cell that charges based on ambient daylight and artificial light. These sensors, respectively, measure the illuminance level and occupancy over their sensing regions. An ambient illuminance-aware sensing protocol is used to communicate this information...
