Creating a Normalized Vegetation Index Sensor with two ...

Aug 30, 2019· Electrically speaking, there is little difference between an LED and a typical photo-diode sensor however an LED’s capacitance is considerably smaller. ( 25 – 60 pF) The tiny light sensing surface area of an LED (~ squared) only generates about 50 pA of discharge current in normal ambient conditions, and the reverse leakage through LED’s is exceptionally low (~ pA).
