Abstract
Techniques are disclosed for detecting changes in occupancy as well as the number of occupants within an area. Detection of one or more occupants entering or leaving the area may be accomplished using a sensor having a quantity of pixels. The pixels may be configured to receive thermal energy emitted from one or more objects present in the area, including from one or more occupants. In response to receiving the emitted thermal energy, the sensor may be configured to create thermal images of the area. These thermal images may include a plurality of thermal intensity values associated with one or more pixels of the sensor. Two or more thermal images can be compared to identify a change in thermal intensity values. A change in the occupancy of the area may be determined by based on the identified change in thermal intensity values.
