Hello,
while doing an experiment of measuring light intensity using LDR with DAQ, +5v is connected with 100k ohm resistance and LDR is connected in series to the ground, the output is taken between these two resistors to an analog input pin(voltage divider).
i make labview program to read the signal that comes from the LDR.
the problem was that it gives 100hz noise signal always. i dont know the reason of why this happening.
so, why do i get noise in the LDR signal at 100hz ?
and how do i get rid of it ?
thanks
