Group:
For this week, our focus was on gaining a few more test trials of the system.
Showing the system displaying the correct output number based off the weather conditions.
We took the Roadway Monitoring system to a larger highway in sunny and rainy conditions. We collected data for the sunny conditions vs rainy conditions.
The video above is one of out test trial conducted in light rain. We began by covering the sensors with an umbrella in order for the system to think there were no conditions that would cause the system to chnage speed, This was done in order to show the system starting at deault speed. We then remove the umbrella to allow the sensors to detect the weather condition. The output values that are being recieved are showing on the laptops in the video. One computer is showing the output of the sensors while the other computer is showing the data collected from the secondary Arduino.
The video above is demonstrations like the previous video but in sunny conditions.

This week:
I completed the graphs that involved precipitation as we wrapped up out real-time test trials.
There was a total of 5 test trials that specifically involved precipitation.
I managed to obtain accurate readings of the required current needed by the system. This is an effort to try and compare the original power budget to the actual current the components were pulling. It turns out that there are a few components that pull less current than previously expected, especially the photocell and the rain detector. Ultimately, this brings longevity to the battery powering the system
The remaining of time was spent of the paper as we completed our test trials.

I have been troubleshooting the numbers displays to determine the reason for the decrease in the display clarity. The wire connections have been stripped again and reconnected to ensure there is no connection issue. I have tried replacing the resistors for new and bigger resistors to ensure there were no bad resistors. A new breadboard was tested to ensure the current breadboard wasn't an issue. My conclusion has led to either continuous sun exposure decreases the effectiveness of the displays or too much heat was provided to close to the numbers when applying waterproof heat shrink to secure the wires. Since, the project is solely for proof of concept, the current number are sufficient enough. Different number displays will need to be chosen for the actual product that will be bought for the road.
The remainder of this week was focused on the completion of the report for the deadline given as 7/5/22.
