Week Log

Monday 26 April 2010


First day of the week log. For some reason recordings stop after approximately 7h. The battery lasted all day. It might be something about the file format. I’ll try with a CSV file overnight to see if it can store more. If it doesn’t work then I’ll have to device the whole day in 800 measurements. If I want to cover 13 hours approximately it means that I can take 61 measurements per hour (800 / 13 = 61.53). So every minute.

Using a CSV file overnight allowed to record many more values. At least 2874 and I stopped it. So this is the graph. I think I must have switched off the light at about 11.45pm. I stopped the recordings at 7.20am. Below is a bigger view of the last section when the light progressively increases:

Measurements were taken every 10 sec, that is 6 readings per minute, 360 per hour. Numbers on the horizontal axis are given in intervals of 180 measurements which equates to 30min (2161, 2341, 2521, 2701). The last value was 2,874 which is when I woke up and stopped it. Sunrise time was today at 5.38am (data taken from http://www.schoolsobservatory.org.uk). So this last bit is almost two hours of progression. Around 2,623 there is a steep increase (maybe when the sun went over the buildings line). Note that the light sensor was in my room with the blinds down.

Below is a picture taken at 8.30am with the exact exposure parameters we were using for the Sun Calendar: 1/60, f4, ISO 200. Massive difference in light intensity from a sunny day in winter!

The battery run out and I have a gap of 1h 30min. This is the first part of the graph that goes until 2pm. Click on the images to see them bigger.
