The analog blocks of PSoC can be used to process the signal from a PIR (Pyroelectric Infrared) motion sensor and detect the presence of objects that emit infrared light. This Application Note describes an application where PSoC is used to detect the presence of human beings to control an electric load. This circuit can be used for controlling a porch light or operating a door.
