There is a new version of Pulse Sensor code now up on our Code Downloads page!  The new version (version 0.6)  is a significant update and we advise everyone to use it.   From our tests, it makes the Pulse Sensor more accurate and reliable on whole.

In detail, changes include:

1)  A digital filter for better signal processing.

2)  Automatic update of heart rate (BPM).

3)  Automatic update of time between beats (HRV) with 1mS resolution !

4)  Sensor data samples are taken every 1mS, timed by an interrupt generated by Timer1.

5)  Access to both raw sensor data and filtered sensor data (b/c we know you want that) !

Happy New Year Everybody !
