Zilog’s ZMOTION Detection Module is a complete motion  detection solution that includes a passive infrared (PIR)  sensor, Fresnel lens, and MCU. PIR technology combines the  unique features of the Z8 Encore! XP®with powerful new motion detection algorithms, providing a dramatic  improvement in both sensitivity and stability.


The Z8 Encore! XP MCU features a high resolution Sigma  Delta ADC that, when combined with the statistical  processing motion detection algorithms, eliminates all  external active and discrete components required in  traditional designs.




Used in lighting controls, access control, display systems, and general-purpose proximity sensing applications, it is also an easy way to add energy management capability to various applications, such as vending machines and appliances.


Two modes of operation are supported:


  1. Serial Mode - Command, control, and configuration is performed over a simple 9600-bps asynchronous interface.
  2. Hardware Mode - Standalone motion detection with analog inputs for sensitivity, output on time control, and ambient light detection.


Additionally, users can create their own applications for the module while taking full advantage of the PIR motion detection technology. The detection pattern covers a 60- degree cone typically out to 5 meters - perfect for general-purpose motion detection.
