how to connect LM35 with myDAQ (external Circuit)?

[hamdouch1000]

hi everybody my supervisor requires me to use the NI myDAQ and he ask me to create an external circuit in order that I may accquire data using the map and the circuit I want to know the contents of this circuit and the appropriate VI!! help please

Hey,

Checkout the LM35 datasheet.  It has recommended application circuits.  You can connect the LM35 to a myDAQ analog input, then in LabVIEW use the DAQ Assistant to read the analog voltage, and then scale it to temperature (the equations you'll need are also in the data sheet).

Let us know if you have any specific questions about this.

Thanks!

Hello every body i need help about the vi that i download in this conversation  it dosen't work with the sensor LM35 when i connect it to Ni mydaq i don't know where is the problem exactly because when i connect sensor and i use vi (just an example for demonstration) that read only the LM35 sensor it work perfectly please i just want to know why this vi dosen't work ?
