6.Operating Precautions

6-1 Basic Principles

PaPIRs is a pyroelectric infrared sensor that detects variations in infrared rays.

However, it may not detect in the following cases: lack of movement, no temperature change in the

heat source. Besides, it could also detect the presence of heat sources other than a human body.

Efficiency and reliability of the system may vary depending on actual operating conditions:

1) Detecting heat sources other than the human body, such as:

a) small animals entering the detection area

b) When a heat source for example sun light, incandescent lamp, car headlights etc, or strong light

beam hit the sensor regardless inside or outside the detection area.

c) Sudden temperature change inside or around the detection area caused by hot or cold wind

from HVAC, or vapor from the humidifier, etc.

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,

b) Non-movement or quick movements of the heat source inside the detection area.

(Please refer to 4-1 for details about movement speed.)

3) Expansion of the detection area

In case of considerable difference in the ambient temperature and the human body temperature,

detection area may be wider apart from the configured detection area.

4) Malfunction / Detection error

Unnecessary detection signal might be outputted, on rare occasions, come from sudden outbreak

output due to the nature of pyro-electric element. When the application does not accept such

condition strictly, please implement the countermeasure by introducing pulse count circuit etc.

6-2 Optimal Operating Environment Conditions

1) Temperature ： Please refer to the maximum rated values of 4-2.

2) Humidity Degree ：15～85% Rh (Avoid condensation or freezing of this product）

3) Pressure ： 86～106kPa

4) Overheating, oscillations, shocks can cause the sensor to malfunction.

5) This sensor is not waterproof or dustproof. Avoid use in environments subject to excessive

moisture, condensation, frost, containing salt air or dust.

6) Avoid use in environments with corrosive gases.
