TIDA-00378: Appropriate IR LED and photodiode for TIDA-00378 design

Part Number: TIDA-00378


 For TIDA-00378 design,which IR led and photodiode will be appropriate? What should be optimal wavelength of these components?

  • For this design we re-used the optical chamber, LED, and photodiode of the Sharp dust sensor (GP2Y1010AU0F). The exact part numbers are not known, but based on research papers on this subject, particle sensors like this one use a wavelength of 940nm.
