Max is still working on improving the battery life performance of the sensor so that it performs closer to our requirement of a week-long battery life. He continued testing this week without LM7805 linear voltage regulator, and the the results resembled the previous battery life of a little less than 3 days. We plan to test this again with different software so that the period between HTTP requests is longer to match the sensor behavior in the gym.
No changes have occurred, but Max is still looking to see if a voltage regulator is necessary in the sensor circuit.
Sid is currently working on improving the accuracy of both models being used for prediction. This week, he continued testing standard models to compare their accuracies, and experimented with using a variety of input variables to find correlations. We plan to use a larger amount of data, which would include points collected over the last month via the sensors.
We are looking to finalize our deliverables for this week, and are preparing for the final demo. The sensor case has already been made, and everything will be soldered and assembled at the start of this week.
