Temperature Sensor interferance with other Analog devices
anonymous 2012-04-02 13:21:20 5813 Views3 Replies If i use the Analog Linear Temp. Sensor (ALTS) in combination with the Analog ambient Light Sensor or the Analog Grayscale Sensor the ALTS gives erroneous and random readings. The ALTS is stable on its own (though not very accurate). I don't believe its the sketch becuase if i disconnect the Light or Grayscale sensor the ALTS will go back to reading consistently. I've tried changing the pause timing, power settings, which analog inputs are used for which device.
suggestions?
Thank you

Thank you

doesnt seem to make any difference. Any other ideas?

What are you using to provide power? The temperature sensor is very sensitive to variations in voltage and current. If you do not provide sufficient or stable power it will cause fluctuations in its accuracy.
