I used the graphs of the datasheet to compare my results.
Here are the results i got while testing the CO sensor in Air :
initially when no heater voltage applied,it was 1.78v
heater voltage at 0.6v ==>output voltage 1.83v ---- 1.82---- 1.81 1.8
at 3v at the first second 2.4v
then quickly 1.8 --- 1.74 ---1.73
at 0.6 v at the first second 4.2v
then quickly 3 --- 2.3 ---1.8--- 1.79 fixed at this value
Comparing it to the graph, i think it is ok, am i right ?
