Abstract

Ceiling fan operation control for turning the fan on and off based on a passive infrared sensor, combined with a temperature sensor to regulate the speed of the fan. The passive infrared sensor, the temperature sensor and controls for both are in a housing directly mounted to the fan motor of the ceiling fan. The controls can be set screws covered by a removable cap. The passive infrared sensor can include a fresnal lens for sensing a 360 degree circumference beneath the fan, and a photo-optical sensor such as a photocell, which suspends ceiling fan control changes for allowing the fan to continue operation when the room is dark and occupants may be sleeping.
