1. Brief Introduction
This handbook has been produced to assist contractors and whole sale rs in
selecting the best location for a sensor and it explains how to installation and
sensitivity controls to appropriate settings to get the best performance from the
unit.
The PIR-100B is a wireless PIR motion sensor, it equipped with Microcontroller
and internal wireless Antenna inside, with low power consumption.
2. Background
Passive Infra-Red Sensors have been around since the 1940s, originally being
used for military and scientific applications.
Now the technology is being used in a wide range of products designed
specifically for commercial and domestic security applications.
The PIR-100B is special for indoor applications, eg.: house, office, shop, store
and so on.
3. How Passive Infra-red sensors work
All PIR sensors detect changes in infra-red radiation, in the form of heat emitted
by a number of bodies including people, cars and, to a lesser extent, dogs or
other small animals. The bigger the body, the more infra-red radiation is emitted
and the easier it is for a PIR sensor to detect.
The field of view is the area in which changes in infra-red radiation can be
detected. The field of view can alter with changes in temperature and the size of
the heat source.
The construction of the PIR and the Fresnel Lens divide the field of view into a
number of zones both vertically and horizontally, as shown in the diagram
overleaf.

Each zone is constantly monitored by the sensor. When a person or other heat
source enters any zone, the level of infra-red radiation in that zone increases.
This change is detected and processed by the sensor, switching on the
microcontroller to process.
Providing the heat source (person) continues to move in the field of view, the
PIR sensor will keep processing the changes in infra-red radiation. If a person
stands still in the field of view or moves out of the detection area, the sensor will
not detect any changes in infra-red radiation between the zones after the ‘Time’
period is complete. In order for the sensor to most effectively detect changes in
heat between zones, it is advisable to walk across the zones not up or along a
zone. PIR sensors are passive devices; they do not emit or radiate any energy
or beams.
In order to save the power consumption, in the PIR-100B, we reserved two

optional for users. One is the Time Span=4 minutes, another is Time Span
=8 minutes. Means once the sensor triggered, then will not trigger again
within 4(8) minutes, after 4(8) minutes, if triggered, then will trigger the
alarm again.
4. Effects of Temperature Changes On PIR Sensors
All PIRs operate by detecting the temperature difference between the ambient
air temperature and a moving heat source (person).
Outside air temperature changes have the greatest effect on the operating
performance of PIRs. The sensitivity of the sensor will increase in cold nights
and decrease in hot nights.
On cold nights, the difference in temperature between a person (normal body
temperature is 37℃) and the outside air temperature, is relatively large, giving
an apparent increase in performance of the sensor. On hot nights, this
difference in temperature is relatively small and a decrease in performance of
the sensor can be expected.
At 15℃ – 20℃, the sensor should perform according to the stated spe cifications.
If the ambient temperature increases to 30℃ or more, the following changes
occur:

1) The maximum distance and field of view significantly decrease (up to as
much as 50%).
2) The distance a heat source has to move across the zones to activate the
sensor increases.
3) The size of the heat source required to activate the sensor increases.
At an ambient temperature of 10℃ or less, the opposite occurs:
1) The maximum distance and field of view increases.
2) The distance a heat source has to move across the zones to activate the
sensor decreases.
3) The size of the heat source required to activate the sensor decreases.
Tips:
1) Nuisance tripping is usually more prevalent in winter. In the summer, problems of
short detection distance and reduced field of view occur more often.
2) The effect of temperature on range and field of view is easily corrected by changing
the angle of the sensor head. eg angle up for summer or angle dow n for winter.
Alternatively, if the unit has a sensitivity adjustment f eature, increase the sensitivity
during summer and decrease the sensitivity during w inter.
5. Typical Construction of PIR Motion Sensor

1) Multi Element Fresnel Lens
The lens focuses the infra-red radiation given out by a heat source (person) on
to the Pyroelectric sensor. The different elements or facets of the lens divide the
incoming infrared radiation into vertical and horizontal zones.
2) Pyroelectric Passive Infra-Red Sensor
The dual element Pyroelectric sensor receives the incoming infra-red radiation
from the various zones. The two elements of the sensor receive varying
amounts of infra-red radiation and this difference is amplified, turning into a
signal via the IC. This signal activates the microcontroller. The sensor detects
infra-red radiation in the wave length range of 8 to 14 m.
3) Integrated Circuit Control Chip (IC)
This is a customised chip which controls the various modes of operation, timing
functions and the processing of the signal from the sensor to drive wireless
alarm signal to alarm panel.
6. Mounting the PIR Sensor
The key to successful operation of any PIR sensor is choosing the correct
location. A sensor mounted in an unsuitable location has the potential to cause
nuisance tripping and reduced performance. The main rules that should be
followed to ensure trouble-free operation are:

location.The greater the field of view, the greater the chance of nuisance
tripping.
