A couple of weeks back I had a look with Richard at the software for reading the data from our sensor. I found it hard to make sense of the data and so did Richard 🙂 There apparently is a lot of noise from the sensor itself which obscures the results / makes them hard to interpret.
Richard said we needed to filter out the results. We worked on that for a bit and he even asked a friend of his to write some code. But it’s a bit too complex for the Arduino, especially if the code had to run real-time.
So another option is to improve the sensor to get better data. For that we need extra parts on the sensor. Richard mailed me a shopping list of parts which I bought last Saturday. This means that the sensor will stay the same but that we’ll need an extra (small) board to stabilize the data. Richard and I will start to work on this soon.
