Reading sensor with current ouput with Arduino I am having diffuclt times with this sensor, so I kndliy ask for your help!
The sensor is named "SPUVA-CS-C3535-A", datasheet here.
The sensor I use (cs3535) has just two pins (+ and -).
From my undesrstanding the ouput is a current corresponding on the UV light exposed to this sensor.
Max value of the current is difficult to understand from the datasheet that also do not have a typical suggested circuit. It seems that a medium value is 200nA, it seems really low!
I have connected (+) of the sensor to 3.3V, (-) of the sensor to A0, and a 220ohm resistor from A0 to Gnd. But readings are always 0.
Any help would be really appreciated! Thanks
The "sensor" is just a photodiode that is sensitive to UV. You use it the same as any photodiode.

The simplest (and crudest) way is to use a very large (eg 1MΩ) pullup resistor to 5V on an ADC pin, then connect the sensor (reverse biased) between the ADC pin and GND.
