2-4 About Sensor
2.4.1 Temperature range
：
-20
℃
~ +60
℃
2.4.2 Detection angle and range
：
90
℃
2.4.3 Detection range: 5m
2.4.4 Note for Using
2.4.4.1 When dust is adhesive to the lens, detection performance will be effected.
2.4.4.2 The lens is made of soft materials. After the load or shock is imposed on lens,
performance deterioration will happen.
2.4.4.3 It will be destroyed by imposing static electricity over +/-200V, thus, be avoid to
touch terminal etc. by hands during operation.
2.4.4.4 Do not clean the sensor by water, otherwise, the liquid poured into the lens will lead
to performance deterioration.
2.4.5 Precautions
DP-PIR01 is only required to be installed inside room, as the location and way of
installation matters the accuracy. The correct way of installation should be required as
below:
2.4.5.1 The sensor should be 2--2.2m far from the ground.
2.4.5.2 Far from the place where there is a temperature variation such as air-condition,
refrigerator and stove
.
2.4.5.3 There should not be substances such as furniture, big-sized plant, glass and curtain
between DP-PIR01 and the detested person.
2.4.5.4 Forbidden to be directly facing the window, otherwise, false alarm will occur by heat
and persons outside.
In addition, degree of sensitivity to human body also matters direction of body movement.
The sensor is not sensitive to radial movement, but sensitive to transverse direction
movement (shown as below).
So, it is very important to install the sensor in an appropriate position to get the best detection.
