Infrared

[ruralcoder]

In your blog you have a section on infrared. I happen to have the NoIR camera with my Model B 1.2 RPi.

"""For some reason that I have not investigated this spectrogram does not capture light into ultra-violet. However it will capture infra-red light if you use a NoIR camera. In order to display a spectrogram covering this range edit the variable w2 with in the code."""

Can you guide me more on what you meant with edit the variable w2.

Currently I see the value at w2 = 780.0.

I changed mine to w2 = 1000.0. What's the actual value I should use?

What about the thresholds
thresholds = [380, 400, 450, 465, 520, 565, 780]
