The unique features of the Z8 Encore! XP
®
MCU have permitted a revised look at the
traditional PIR based motion detector design. Combined with innovative software
techniques, this new approach has overcome the typical performance limitations of the
traditional design.
This “fresh” look has produced a revolutionary step in PIR detector technology called:
ePIR™ with Sigma Delta Technology
TM
ePIR with Sigma Delta Technology combines the high performance and rich peripheral
set of the Z8F042A Encore! XP MCU with powerful new motion detection software
algorithms to provide exceptional motion detection performance.
Taking full advantage of the high processing capabilities of the Z8F042A MCU, ePIR with
Sigma-Delta Technology uses a powerful new statistical processing method to provide
superior sensitivity and stability vs. traditional solutions.
The software automatically adapts to the environment eliminating the need for discrete
temperature compensation.

APPLICATIONS
Lighting Control
Conveniently turn lights on
automatically
Direct interface to the PIR sensor provides a true, unaltered signal, allowing the software
to identify and react to drift, sensor stability and other false alarm sources.
This direct interface also eliminates the need for external components including large
electrolytic capacitors; improving reliability and ensuring the smallest possible form factor.

automatically turning off lights
when people are not in the room
Lights do not turn on when
ambient light is sufficiently high

The ePIR Motion Detection Zdots SBC uses a Fresnel lens to break up the radiated IR
energy into multiple concentrated images. These images are refracted on to the element
of the PIR sensor which generates a signal based on the change in energy. The signal is
fed directly to the Z8 Encore! XP MCU where it is analyzed by the motion detection
algorithms to determine if it is from a valid source.
Parameters for sensitivity and output timing are provided through a simple hardware
interface or more advanced settings and status are available through a serial interface
mode.

Advanced configuration and status via serial interface
/MD, LG and /SLP remain functional
The serial interface runs at: 9600 bps, no parity, 8 data bits and 1 stop bit
Provides access to additional features:
Wider selection of activation times, sensitivity and range
Low frequency rejection
Pulse count
Directional detection
Dynamic PIR Sensor Stabilization
In traditional motion detection designs, critical information about the PIR sensor health
and stability is lost. With a direct interface to the PIR sensor, the ePIR Motion Detection
Zdots SBC is able to dynamically monitor the PIR signal to determine when it has
stabilized. This significantly reduces the required power-on stabilization time.
Detection Pattern
The lens on the ePIR Motion Detection Zdots Single Board Computer provides a typical
range of 5 m x 5 m with a 60 degree angle. The actual distance is dependent on the
sensitivity setting of the ePIR Motion Detection Zdots SBC.
