EKPS021C3

Commodity Name: Light sensor EKPS021C3

Commodity Category: Light sensor

Commodity Model: EKPS021C3

Light sensor, with a chip built in, is sensitive to ambient light. Its photopic response is close to human eye. Being compliant with RoHs, it can be used as  replacement of Cds photocell.

 

 

 

Features:
  Special filter epoxy encapsulation;
  Special response characteristics similar to the human eyes;
  Linear output with light changes;
  Have certain temperature stability;
  Low dark current,low intensity of illumination.

Typical Applications:
  Direct replacement of CdS LDR;
  Adjust background light,such as PDA,television,Cameras,
  LCD/LED displays and mobile phones,etc.;
  Electronic toys and lighting equipment
