Abstract
A light fixture can include a housing and a sensor device having a sensor that measures at least one parameter associated with a position of the housing. The light fixture can also include a controller coupled to the sensor device. The controller can receive multiple measurements of the at least one parameter taken by the sensor device. The controller can also evaluate each measurement against at least one range of acceptable values. The controller can further send a notification when a measurement falls outside the at least one range of acceptable values. The notification can state that the housing is moved out of position and requires attention.
