jremington:
There are many things wrong with that schematic, and you still have not told us what you want the circuit to do."Sensor 1" is not defined. Photodiodes have two pins, not 3. Post a link to the part.
C2 will prevent any DC voltage from the sensor being applied to the op amp input.
What is R3 supposed to do?
What is R2 supposed to do, and why is it connected from +5V to +5V?
Sensor 1 is TSL14S that is a light to voltage converter.
