General-Purpose Dual Element Pyroelectric Infrared Radial Sensor

The pyroelectric infrared sensor detects infrared radiation on the basis of thecharacteristics that the polarization of pyroelectric material changes with temperature.Dual compensated sensing elements are applied to suppress the interference resultingfrom temperature variation. As a result, the operating stability of the sensor is greatlyimproved. 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 ofelement ichnography. Combining with focus of Fresnel lens can achieve a optimaloptics design.

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

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

4. The welding shall be made at 4mm above as per the recommendation for leadwire 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 thesensors’surface has been covered specially with OHK anti-erode material,100pcs per small package ,3000pcs per large package.
