Reference Design: ZMOTION AC Load Controller Design Module (ZMOTIONAC00MODG)

Zilog’s ZMOTION AC Load Controller Design Module demonstrates how to use Zilog’s ZMOTION MCU in a passive infrared-based motion detector to control power to an AC load in applications such as lighting and HVAC systems. The design uses the 8-pin Z8FS040 MCU to intelligently control a mechanical relay, and provides user adjustments for motion sensitivity, delay time, and ambient light level.


This reference design consists of a single PCB that connects directly to an AC line and controls power to an AC load via a relay. However, to test different lens combinations, or to perform in-circuit programming, consider the ZMOTION AC Load Controller Design Kit, which includes this PCB plus a USB SmartCable and a selection of lenses.


Key Features

  • Controls power to an AC load based on motion detection
  • ZMOTION PIR Technology provides immunity to EMI/RFI and other false trigger sources
  • 120 VAC/240 VAC 60 Hz/50 Hz input/output
  • Switched AC line output for loads up to 5 A (limited by fuse and relay)
  • Adjustable sensitivity, delay, and ambient light gate level
  • Adjustments can be made from front or back side of board
  • Supports six lenses with various patterns and ranges
  • Smart Delay feature for pass-through events
  • Delayed Detection Mode for harsh conditions
  • Small two-layer single-board design, with a 2.7" x 1.7" (6.5cm x 4.3cm) footprint

Potential Applications

  • Occupancy-based lighting control
  • Doorway/hallway lighting control
  • Closets and other small rooms
  • Office cubicle lighting and power control
  • Kiosk power control
  • Retail displays
  • Entrance and exit control
  • Appliance power management
  • HVAC Control

The ZMOTION AC Load Controller Design Module includes all of the hardware necessary to develop prototypes and projects incorporating the host and peripheral functions on Zilog’s wide selection of MCUs.
