Hi,
I was wondering if you lovely people could comment on the feasibility of a using my Uno with two Si APDS for to detect fluorescence intensity coming through a .4 mm single core FC patch cable.
What I managed to get my hands on is a Hamamatsu S1227 si photodiode with a Max reverse voltage of 5 V.

Am I mistaken in thinking that I should be able to get a decent digital readout with a 1M resistor and a decent op amp for that range, and if so, I presume the 741 wont be any good at that voltage. Can you point me to any circuit suggestion? I have seen the template ones on their website but am struggling a bit with suitability? Also any suggestions on how I can mount my FC patch to the diode?
Also, have a +15/-15 V Apd that I am trying to run off a voltage divider, but worried about the output voltage and my arduino.
Happy Easter and thanks so much for any suggestions
