Motion Detector Test Results
Purpose:
This document contains the test results for Phase 2 detector.
Summary:
The motion sensor works well and meets standby current spec <42.3uA average. It also works well over
target voltage range of VDD = 2.7V to 3.5V using an E1 emulator, CR123 battery or external power
supply. Some initial setup of 3 pot settings is required.
Test Results as per Test Spec:
TEST
1. Motion detector will be placed
near the edge of a countertop or
table top at 24”-36” above the
floor. Motion detector PIR
sensors will pointed out in a
horizontal direction and should
not be obstructed by the table
edge or countertop edge. The
tests will be performed in an area
where there is no direct sunlight
and no heat/IR lamps present.
RESULTS
OK.

(typically VDD =
3.3V-3.5V). Then
set JP11 pot for
IVREF0 (DNI_J2,
Pin 12) = 0.86Volt
and set JP10 pot
for IVREF1
(DNI_J3, pin 1) =
2.3Volt. Set JP9
pot for about 50%
2. A human with mass of 50kg or
greater can be the test subject and
can be used to roughly calibrate
the Motion sensor. First the
potentiometer gain should be set
to minimum setting and with the
test subject standing 4 meters
(~13 ft), the PIR 2nd stage pot gain
should be increased to where the
motion alarm starts to sound.
3. After calibration a human subject
should approach the PIR sensor
from a distance greater than 6
meters from 5 different angles
described on the surface of a 90
degree circular cone with the apex
point of the cone intersecting the
surface of the PIR sensor:
a. Straight on axis to the PIR
sensor.
b. From >70 degrees off-axis
to the right (“3 o’clock“
position) to the 45
c. From >70 degrees off-axis
to the left (“9 o’clock“
position)
d. From >45 degrees off-axis
down toward the floor (“6
o’clock“ position)
e. From >45 degrees off-axis
above the Motion sensor
(“12 o’clock“ position)
If I set the AMP0O
gain for max value,
I can get motion
detection at about
4.5-5Meter for on
axis placement
and about 3Meter
distance at 70
degrees off axis.

gain for max value,

distance (4Meter?)

external power),

AMP0O set at max
gain (JP9 at full
CW position) is
probably too
sensitive and may
result in false
Motion sensing.
4. At the angle and distance the
alarm sounds, the approximate
distance should be measured, and
should at least (and is allowed to
be greater than) 3 meters distance
minimum and at an angle =/> 45
degrees from the on-axis line
5. When the detector senses motion,
it should alarm for a minimum of 1
sec and keep the alarm on for a
minimum of 1 sec after motion
ceases to be detected and
continuously when motion is
detected otherwise.
6. Then to test the motion velocity
sensitivity, the motion detector is
allowed to alarm from any
movement of the Human subject,
but is not required to do so for
motion velocities < 0.05 m/sec or
>5m/sec.
7. Also for the PIR sensitivity test, a
human subject inside the
maximum detection range of the
motion detector should not trigger
the alarm if the subject is
completely motionless.
8. Fluorescent or CF lighting outside
the 3 meter radius of the sensor
should not trigger the PIR sensors
9. Confirm that pushing the SW1
button (added on the Phase 2
Motion sensor board) will sound
the alarm as long as the button is
pressed and turn off when SW1
button is released (assuming no
motion in front of sensor).
10. Current drain measurements and
associated duty cycles for each
type MCU operation will be
measured for the Motion sensor
operation in:
a. Standby mode with no
motion in the field of

When measuring
current drain with
external power
supply, make sure
keep milliameter
on high milliamp
scale to allow 5070mA (alarm
current). Many
milliameters will
starve the current
drain when on
200uA max or
2mA full scale
ranges. When
starving the
current, VDD
voltage drops too
low and causes
