This sensor has an optical heart rate sensor with amplification and circuit for noise reduction, giving fast and reliable pulse readings.

Muscle Sensor

The electromyogram (EMG) sensor detects electrical activity from a muscle using conductive pads placed on the skin. Every time the muscle is activated, individual fibres within it receive electrical impulses, causing them to contract. The MyoWare Muscle Sensor to which this shield attaches is an Arduino-powered, all-in-one electromyography (EMG) sensor from Advancer Technologies. The MyoWare board acts by measuring the filtered and rectified electrical activity of a muscle, outputting 0-Vs Volts depending on the amount of activity in the selected muscle, where Vs signifies the voltage of the power source.

Pulse Sensor

A pulse wave is the change in the volume of a blood vessel that occurs when the heart pumps blood, and a detector that monitors this volume change is called a pulse sensor. The Pulse Sensor Amped is a plug-and-play heart-rate sensor for Arduino. It can be used by students, artists, athletes, makers, and game & mobile developers who want to easily incorporate live heart-rate data into their projects . It essentially combines a simple optical heart rate sensor with amplification and noise cancellation circuitry making it fast and easy to get reliable pulse readings.
