Help.. we're making a light measuring circuit as part of our thesis project.
I need a circuit which can convert the amount of light received into a voltage level.
I tried using light dependent resistors but it lacks sensitivity because we are measuring underwater in dark conditions and we are using an optical filter which only lets light around 680 nm wavelength pass..
I'm out of ideas..
