Power management control device

A power management control device comprising:

• a controller configured to be mountable to a substrate proximate to a doorway, the controller being configured to operationally engage an electrical circuit of a structure, such that the controller is operationally engaged to at least one electrically powered device in at least one room of the structure to which the doorway allows entry, wherein the controller is configured for selectively actuating the at least one electrically powered device, the controller comprising:
• a housing defining an interior space,
• a microprocessor attached to the housing and positioned in the interior space, and
• a control panel attached to the housing and operationally engaged to the microprocessor, wherein the control panel is configured for manipulation by a user for inputting commands into the microprocessor, the control panel comprising:
• a first switch configured for being switched for turning on the at least one electrically powered device,
• a second switch configured for being switched for turning off the at least one electrically powered device, and
• a third switch configured for being switched for enabling the microprocessor for selectively actuating the at least one electrically powered device;
• and
• a sensor module configured to be mountable to a doorframe defining the doorway, the sensor module being operationally engaged to the controller and configured for detecting passage of a person through the doorway, wherein the sensor module is configured for detecting passage of persons through the doorway and for signaling the controller, such that the controller is enabled for maintaining a count of persons in the at least one room, enabling the controller for actuating the at least one electrically powered device upon entry of a first person into the at least one room and for deactuating the at least one electrically powered device upon exit of a last person from the at least one room, the sensor module comprising:
• at least one infrared emitter configured to be mountable to a first jamb of the doorframe, and
• at least two infrared detectors configured to be mountable to a second jamb of the doorframe, such that the infrared detectors are positioned for detecting infrared light emitted by the at least one infrared emitter, the infrared detectors being substantially linearly spaced from each other in a direction parallel to a path which extends through the doorway, such that the infrared light to the infrared detectors is interrupted sequentially as a person passes through the doorway, such that the controller is enabled for sensing and differentiating between the person entering the at least one room and exiting the at least one room.
