Hello friends
I am making a sensor using photodiode. photodiode's following values are changing when light from LED is passed through different specimen:
without biasing - just when a digital mutlitmeter is connected, the resistance of the photodiode alters for every specimen. but it keeps increasing and does not stay at constant. can I use dI/dt instead?
Thanks
