LPS331AP pressure sensor test flight

We expect to release a simple carrier for ST’s new LPS331AP pressure sensor this week. While testing and writing example programs for the sensor, one of our engineers, Kevin, came up with a nice demonstration that calculates and displays the altitude on our Orangutan SVP robot controller. It was a beautiful spring day with great flying weather, so Paul and I took Kevin’s digital altimeter on a flight to Lake Havasu City, Arizona, to see how it compared to the altimeter in a plane.

I and several others at Pololu have since had some more personal deliveries of the crying-all-night sort, which delayed my promised update. I still do not have the performance information I had hoped to have by now, but let’s at least look at what we got: Continued…
