Description
The D205B pyroelectric infrared sensor detects infrared radiation on the basis of the characteristics that the 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.
Features
- The junction field effect transistor realizes impedance transformation in the form of source follower
- The dual-element compensation structure is adopted to effectively resist the interference of environmental changes, vibration and stray light
- Suitable for automatic lighting switches, smart toys, intrusion detectors for burglar alarms, various household appliances, etc
