Abstract
Methods and apparatus associated with monitoring and controlling streetlights include monitoring light levels and voltage levels at corresponding streetlights and controlling the streetlights to set or maintain a particular light output at the respective streetlights or providing power consumption estimates for respective streetlights (streetlight specific metering) based on the voltage levels and light levels. A streetlight controller for a streetlight includes a microcontroller; a first sensor to sense a light level from a lamp within the streetlight; a second sensor operative to sense a voltage level on a power supply for the streetlight; and a switching network coupled with the microcontroller and operative to adjust the light level of the lamp. Methods includes monitoring a light level and voltage level and adjusting a light level, estimating power consumption, or facilitating maintenance in accordance with the light level and voltage level. The methods may be performed all or in part at a streetlight, a local gateway or a central controller and database.
