Review on 💓 PulseSensor Com Original Pulse Sensor Project: Track Your Heart Rate with Precision! by Mike Walters

PulseSensors arrived on time, no damage. The sensor must be protected before use. There is a clear vinyl pad on the front and hook and loop fasteners on the back. The (good) instructions say to seal it with hot glue, but I'll do that later. The examples given are good and work perfectly. Only the pressure that you exert with your finger is decisive. Fairly light pressure has worked best for me, but it's difficult to maintain consistently. Maybe a big clip, like in hospitals, would make it easier. Haven't tried the clip-on option yet.
