Tragoods Heart Rate Monitor Sensor for Arduino, Pulse Sensor Plug-in for Arduino, Pulse Sensor Pulsesensor Sensor Module

Worked great on the project I made. Easy to use.

Senser work well but not sensitive .

This was great just what I wanted thank you!

Readings are very off and constantly jump around to vastly different values. You would get more consistent results just using a random number generator.

The wiring diagram on this listing is hilarious. You picture SIG on the sensor being connected to N/C and then + AND - connected together to IOREF (which would do nothing.) Then additionally you have diagrammed out "Power" without polarity being marked, to A0 and A1, which would also likely do nothing unless you did some really weird software configuration, which would *STLL* be incorrect.

Everything works as expected.
