Pyroelectric ir motion sensor

A non-transitory computer-readable medium, comprising:

• instructions stored by the non-transitory computer-readable medium, wherein the instructions are configured to cause a processor to:
• initiate receiving pyroelectric IR (PIR) sensor array data;
• initiate extracting angular position features from the PIR sensor array data;
• and
• initiate identifying the relative angular position by applying a pattern matching algorithm to the angular position features.

An apparatus, comprising:

• a processor;
• and
• a memory coupled to the processor and configured to cause the processor to:
• initiate receiving pyroelectric IR (PIR) sensor array data;
• initiate extracting angular position features from the PIR sensor array data;
• and
• initiate identifying the relative angular position by applying a pattern matching algorithm to the angular position features.

A method for determining a relative angular position of a target of a motion sensor, comprising:

• receiving pyroelectric IR (PIR) sensor array data;
• extracting angular position features from the PIR sensor array data;
• and
• identifying the relative angular position by applying a pattern matching algorithm to the angular position features.
