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
