Sample Graphs from Logged Data.

This graph shows the light levels and temperature on the shelf above my workbench. The sharp peaks are due to the small amount of natural light that enters my workshop during the day. The flat peaks show the fluorescent lights switched on during late night work on Circuit Cellar design contests. After the first day of 34ºc I switched on the air conditioning, which results in the smoothing of the temperature curves at 28 - 29ºc in the days that follow.

This graph shows the outdoor light levels and temperature over a 7-day period with a 10 minute logging interval. The very high temperature shown on the first day was with the device in direct sunlight. It was moved to a more shaded spot when I noticed the temperature hit 60ºC
