i am not so confirm with electronic but i would like to connect a oxygen sensor to an arduino to messure the oxygen concentration in my office.
so the analog oxygen sensor generate a voltage of 0mv to ca 50mv on 100% oxygen.
Who i can connect this to the analog or digital arduino pin? i think i must work with an opto-coupler and i must a little bit stabilze the voltage from the sensor. i hope that its correct.
can anybody help me?
regards and sorry for my bad english Thomas
