Hello sir/mam I am using daq usb 6210 with labview and i want to take output of multiple sensors using same daq ,can u suggest me how to do this .
i also tried tgs 823 sensor and examined its voltage and current curve which was ok but when ethanol is sensed to the same sensor ,resistance increased instead of decreasing , may be because of the same value of excitation current . so can i put the same value of excitation current as i get through current measurements.

Hi Parulp,
I am using daq usb 6210 with labview and i want to take output of multiple sensors using same daq ,can u suggest me how to do this .
So you want to read more than one INPUT signal using your USB6210 device? Just do so!
(LabVIEW comes with a lot of example VIs for DAQmx, there are also examples explaining the usage of analog inputs…)
so can i put the same value of excitation current as i get through current measurements.
This sensor seems to work as simple voltage divider using that additional R_L in the spec sheet: no need to use a constant current excitation…
