With Zilog’s ZMOTION
™
Detection and Control Solution, the system bill of materials is significantly reduced.
The pyroelectric sensor is directly interfaced to the MCU eliminating external op-amps, electrolytic
capacitors, and other components used in traditional designs. The new statistical processing algorithms
provided by the Enhanced PIR motion-detection engine also eliminate the need for a discrete temperature
compensation circuit.
This all leads to a simpler and smaller circuit design, providing better reliability, sensitivity, and stability
than traditional designs.
