Sensors specifications

[aishu95]

Are all sensors compatible with LabVIEW  and DAQ assisstant or are there any specifications ?

[RavensFan]

Sensors have nothing to do with LabVIEW or the DAQ assistant.

The question is whether you have a DAQ device that is cabable of reading your sensor.

[amazed]

As Ravensfan points out, the burden is on the daq.

From my experience, some sensors require differential inputs on the daq(ie- many single pwr supply sensors)  Also, want  the sensor output to be within range of daq. (some daqs limited on neg side)  Lastly, you want 2 be sure that daq can read  beyond the normal range of the sensor so you can detect an overrange condition.  

good luck

Environment > Sensor > Signal > DAQ Device > LabVIEW > User

This is the general idea.

My guess is you're asking about DAQ Devices in general. LabVIEW and MAX are great at working with a wide range of devices, though NI equipment is obviously the easiest.

How to calibrate MQ-3 sensor using LabVIEW 14.0 ?

[GerdW]

Hi aishu,

such a question should be answered in the calibration manual of the sensor manufacturer!

If the manufacturer of this (cheap) sensor doesn't provide any calibration data/manual you could look for similar (but better) gas sensors and read their calibration manual. Then apply your new knowledge to your sensor…

Hint: to calibrate gas sensors you need gas compositions with known content…
