We present a card-size, photocurrent-based readout platform for spectral sensors based on a wavelength sensitive photodiode. The resolving capacity for wavelength shift and ratiometric measurements is examined using different LEDs. With the introduced setup a wavelength shift resolution of 0.1 nm and a limit of detection of 0.001 for the ratiometric measurement was achieved. On the basis of the obtained results, we discuss several advantages and drawbacks of this interrogation approach for spectral sensors.
