Week 10/20 to 10/26

In this week, we determined to use the digital Hall Effect sensor to do test for scanning the corrugated metal strip. The test was very successful. In this case, we did not have to worry about the corrugated metal strip design. It is because if we try to use the analog output Hall Effect sensor to scan the corrugated metal strip and magnet, then the distance between two peak (up and up), the peak to peak distance(up and down) and the deflection on each curve has to be very accurate. It will be a very big challenge to make this strip. For now, we use digital Hall Effect sensor, the strip only need to focus on the accurate of the distance between two peak (up and up). The design will be shown below.
