Explanation of the timing
Explanation of modes
tWU
Circuit stability time: about 25 seconds (typ.) for 2μA type,
max.10 seconds for 6μA type, max. 30 seconds for 170μA type.
1)
Sleep mode:
When the output is Low. The electrical current consumption is around
1μA
2)
Standby mode:
After the sensor's output has reached High status, the sensor switches
to standby mode. The electrical current consumption gets close to
1.9μA. When the sensor's output returns to its Low value after the "hold
time" has expired, the sensor switches again to sleep mode.
While the circuitry is stabilizing after the power is turned on, the
sensor output is not fixed in the High or Low state. This is true
regardless of whether or not the sensor has detected anything.
3)
Mask mode:
Time during which the output is forced to Low status after the end of the
standby mode. (No detection is possible during this period.)
Explanation of the timing
t1)
(tWU)
Circuit stability time: about 25 seconds (typ.)
While the circuitry is stabilizing after the power is turned on, the sensor
output is not fixed in the High or Low state. This is true regardless of
whether or not the sensor has detected anything.
t2)
t3)
Standby hold time:
Mask time:
About 2.6 seconds (typ.) after the last detection of a signal. (*1)
About 1.3 seconds (typ.) During this stage, even if the sensor detects
something, the output will not switch to High. (*2)

Notes: Digital output types:
The output signal for the digital output type is from inside FET drain, therefore pull-down resistors are necessary. Please select an output resistor (pull-down concept) in accor-
dance with VOUT so that the output current is maximum 100μA. If the output current is more than 100μA, this may cause false alarms.
If the microcomputer has a pull-down function, there is no need for a resistor as long as the output current does not exceed 100µA.
Analog output types (EKMC26 series):
In either case, a microcomputer or a resistor needs to be chosen in accordance to VOUT, so that the output current is maximum 200µA.

PIR MOTION SENSORS
Cautions for use
Basic principles
Cautions
PaPIRs are pyroelectric infrared sensors that detect variations in infrared rays.
However, detection may not be successful in the following cases: lack of movement or no
temperature change in the heat source. They could also detect the presence of heat sourc-
es other than a human body. Efficiency and reliability of the system may vary depending on
the actual operating conditions:
1) Refer to the newest specification regarding optimal operating environment conditions.
2) Do not solder with a soldering iron above 350°C (662°F) or for more than 3 seconds.
This sensor should be hand-soldered.
3) To maintain stability of the product, always mount it on a printed circuit board.
4) Do not use liquids to wash the sensor. If washing fluid gets into the lens, it can reduce
the performance.
1) Detecting heat sources other than the human body, such as:
a) small animals entering the detection area
5) Do not use a sensor after it has fallen on the ground.
6) The sensor may be damaged by 200 volts of static electricity.
Avoid direct hand contact with the pins and be very careful when operating the product.
7) When wiring the product, always use shielded cables and minimize the wiring length to
prevent noise disturbances.
b) When a heat source, for example sun light, incandescent lamp, car headlights etc.,
or strong light beam hit the sensor regardless whether the detection area is inside
or outside.
c) Sudden temperature change inside or around the detection area caused by hot
or cold wind from HVAC, or vapor from a humidifier, etc.
8) The inner circuit board can be destroyed by a voltage surge.
The use of surge absorption elements is highly recommended.
Surge resistance: below the power supply voltage value indicated in the section on
maximum rated values.
2) Difficulty in sensing the heat source
a) Glass, acrylic or similar materials standing between the target and the sensor may
not allow a correct transmission of infrared rays.
9) Please use a stabilized power supply. Noise from the power supply can cause operat-
ing errors.
b) Non-movement or quick movements of the heat source inside the detection area.
(Please refer to the table on page 8 or 11 for details about movement speed.)
3) Expansion of the detection area
Noise resistance: max. 20V (square waves with a width of 50ns or 1μs)
To reduce the effect of noise from the power supply , install a capacitor on the sensor's
power supply pin.
In case of a considerable difference in the ambient temperature and the human body
temperature, the detection area may be larger than the configured detection area.
4) Malfunction / Detection error
10) Operation errors can be caused by noise from static electricity, lightnings, cell phones,
amateur radio, broadcasting offices, etc
On rare occasions, an erroneous detection signal may be output due to the nature of
pyroelectric element. When the application cannot tolerate erroneous detection signals,
take countermeasures by introducing a pulse-count circuit, etc.
5) Detection distance
11) The detection performance can be reduced by dirt on the lens, please be careful.
12) The lens is made of soft materials (Polyethylene).
Please avoid adding weight or impacts that may change its shape, causing operation
errors or reduced performance.
Panasonic's PIR Motion sensors state the detection distance in the specifications
because they are usually provided with the lens (please refer to item 6 for lensless
types). The PIR Motion sensor could detect variations in infrared rays however such
variations are decided by following three factors.
13) The specified temperature and humidity levels are suggested to prolong usage. Howev-
er, they do not guarantee durability or environmental resistance.
Generally, high temperatures or high humidity levels will accelerate the deterioration of
electrical components. Please consider both the planned usage and environment to
determine the expected reliability and length of life of the product.
14) Do not attempt to clean this product with detergents or solvents such as benzene or
alcohol, as these can cause shape or color alterations.
•
The temperature difference between the target and the surroundings:
The larger the temperature difference, the easier it is to detect targets.
•
Movement speed: If the target is moving at a slower or faster speed than specified in
the tables, the detection ability may be lower.
15) Avoid storage in high, low temperature or liquid environments.
Also, avoid storage in environments containing corrosive gas, dust, salty air etc.
Adverse conditions may cause performance deterioration and the sensor's main part or
the metallic connectors could be damaged.
•
Target size: The human body is the standard. If the target is smaller or larger than
specified in the table, the detection ability may be lower.
The detection distance explained in our data sheet is defined by the three factors
mentioned above. Panasonic's standard for the temperature difference between the
target and the surrounding is defined as 4°C. The larger the temperature difference,
the longer the detection distance. If the temperature difference is 8°C, which is twice
as much as the standard, the detection distance will be approx. 1.4 times longer than
the distance at 4°C. For example, if targets at a distance of 5m can be detected at
4°C, then the sensor can detect targets at a distance of 7m at 8°C. (This is based
on the theory that the detection sensitivity will vary inversely with the square of the
distance.)
16) Storage conditions
Temperature: +5 to +40°C, humidity: 30 to 75%
Please use within 1 year after delivery.
6) Lensless Type
The lensless type cannot detect any targets because it is not possible to focus infrared
variations into the sensor chip. It is not possible to determine the detection distance and
the field of view without a lens. Please provide your own lens based on your lens design
concept.
7) Lens material and the plate setting in front of the lens
Typically, the only material that can be passed by infrared rays is Polyethylene.
(The lens material of Panasonic's PIR Motion sensors is "High density polyethylene,
HDPE".) When you need to set a plate in front of the lens, please choose one made from
the Polyethylene. Please note the thickness or color of the plate will affect the detection
ability, e.g. it may make the detection distance shorter. Therefore, please confirm by
testing the sensor with the plate under realistic conditions.
Safety precautions
Obey the following precautions to prevent injury or accidents.
1) Do not use these sensors under any circumstance in which the range of their ratings, environment conditions or other specifications are exceeded. Using the sensors in any way
which causes their specifications to be exceeded may generate abnormally high levels of heat, emit smoke, etc., resulting in damage to the circuitry and possibly causing an
accident.
2) Our company is committed to making products of the highest quality and reliability. Nevertheless, all electrical components are subject to natural deterioration, and durability of a
product will depend on the operating environment and conditions of use. Continued use after such deterioration could lead to overheating, smoke or fire. Always use the product in
conjunction with proper fire-prevention, safety and maintenance measures to avoid accidents, reduction in product life expectancy or break-down.
3) Before connecting, check the pin layout by referring to the connector wiring diagram, specifications diagram, etc., to verify that the connector is connected properly. Mistakes
made in connection may cause unforeseen problems in operation, generate abnormally high levels of heat, emit smoke, etc., resulting in damage to the circuitry.
4) Do not use any motion sensor which has been disassembled or remodeled.
5) Failure modes of sensors include short-circuiting, open-circuiting and temperature rises. If this sensor is to be used in equipment where safety is a prime consideration, examine the possi-
ble effects of these failures on the equipment concerned, and ensure safety by providing protection circuits or protection devices.
Example : Safety equipment and devices, traffic signals, burglar and disaster prevention devices, controlling and safety device for trains and motor vehicles
