General-Purpose Dual Element Pyroelectric Infrared Radial Sensor

The pyroelectric infrared sensor detects infrared radiation on the basis of the
characteristics that the polarization of pyroelectric material changes with temperature.
Dual compensated sensing elements are applied to suppress the interference resulting
from temperature variation. As a result, the operating stability of the sensor is greatly
improved. Our products can be used in many applications. Such as in security systems,
burglar alarms, visitor acknowledgement, light switch control and intellectualized toy, etc.


Directions for Use

1. Pay attention to the mounting direction of the sensor’s element and the size of
element ichnography. Combining with focus of Fresnel lens can achieve a optimal
optics design.

2. The ex-factory parameter of sensor is gained by testing in the condition
standard Black Body and the relevant circuit after one minute steadying-time.

3. The detecting distance of sensor is a multidimensional function, consisting of
ambient temperature, temperature of moving target , target distance of Fresnel
Lens’, ambient humidity , amplifier gain and comparison voltage.

4. The welding shall be made at 4mm above as per the recommendation for lead
wire of sensor seat, and the welding should be completed in the shortest possible time.

5. Do not touch the window by hand and the hard things directly.

6. Strong shake and static should be avoided.

7. This products are packed with the environmental protection material ,and the
sensors’surface has been covered specially with OHK anti-erode material,
100pcs per small package ,3000pcs per large package.
