Hi Mr. Wu,
There are two ways to get data from sensors into CODAP. The first would be to use PASCO’s own software to collect the data, then export as CSV and drop that CSV into CODAP.
We are also working on a plugin for CODAP that will allow direct import of data from sensors. Here’s a CODAP document that has the current state of our sensor plugin. You could use this as a starting point for students.

It’s a bit rough around the edges. We are still working on it, so consider that a temporary link to try this out. We would love feedback from you regarding how this works (or where you find bugs). When we have a more stable and publicly available link I will post that here.
