Thank You tkbyd
I think it is not what I am looking for but it is always good to know that something like that exist
55000/10 bit ADC (1024) = 53,7 . If I am right that will be my accuracy so quite not good considering fact that I am interesting in 40-200 LUX. Second thing is that I don't think so it will work on 50 meters distance.. or maybe I am wrong? Does somebody know what is the max distance to work with such sensors?
The sensor which I mentioned has got two versions: 4-20mA and 0-10V. As I know it's better to use 4-20mA.
0-10V for long distance isn't good choice because of wires resistance but I am not sure about that. If I decide for 4-20mA version do I need to connect it via 250/220 ohm resistor or it's possible to connect it directly to analog Arduino pin?
