General Purpose and Omni-directional Quad Element Pyroelectric Infrared Radial Sensor(D205B)

The pyroelectric infrared sensor detects infrared radiation on the basis of the characteristics that the self-polarization of pyroelectric material changes with temperature. Quad sensing elements are applied to suppress the interference resulting from circumstance temperature variation, to raise signal output and to be sensitive in all directions. This type senor has the technical merits of both single and dual type.As a result, the operating stability of the sensor is greatly improved. It can be widely used in many applications such as in automatic light switch control,security systems, burglar alarms, visitor acknowledgement and intellectualized toy, etc.,especially in the field of ceiling mount applications.


Feature
1. high sensitivity
2. long detecting distance
3. wide angle
4. strong stability
5. wide application fields
6. 2 years warranty


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.
