Usb 6008 + LM35 temperature sensor problem

[cgama]

Thank you veeeery much santiore! It worked perfectly!

Dear Mr Cgama,

I tried to using 220ohm to remove the noise. MY LM35 & DAQ6008 can not give a good result. When I measure 24 degre celcius. I the result was 8 celsius. I can u help?

Hi saifizi

I have used 220ohm like santiore had suggested and it worked great. The V+ connected to 5V on my circuit and the resistor between Vout and Gnd in the temperature sensor. The only thing I may have done differently is not using the differential inputs of the DAQ card. But I have tried both ways and both worked fine. Im afraid I can't help you further as I'm not that knownledgeable. Maybe someone else may give you more insight.

(If you're a rookie like me, make sure all your connection are right!  )

Good luck!

Dear Gama,

The V+ that u connect to 5 volt is V+ at the LM35 sensor right? I think already do the connection like the santiore do it. it is possible the lm35 have different type?

Hi Cgama,

Can u show the pic of connection. Maybe I was wrongly understand your connection.
