Troubleshooting

  • Primary Test: Make sure that the sensor is not picking up the 60 or 120 Hz flicker from fluorescent or other lamps. Eliminate all artificial light sources (except battery powered flashlights) and try your experiment.
  • Secondary Test: Test the Light Sensor positioned as you plan to use it. Set the sampling at 1000 points/second for 0.1 second. If the flicker is the problem, you will see a drastic variation in the light intensity with a period of 60 or 120 Hz (50 or 100 Hz outside North America).
  • Tertiary Test: Set the sample rate to a number that is not a factor of 60. For example, using 30, 20, or 10 samples/s is worse than using 17, 23, 27 samples/s.

Calibration

Calibrate? No. The sensor is set to the stored calibration before shipping. If you wish to calibrate the sensor, there are two options.
