The MyoWare 2 Muscle Sensor is an Arduino-compatible, all-in-one electromyography (EMG) sensor from Advancer Technologies. The MyoWare 2 Muscle Sensor has been redesigned from the ground up with a new easy-to-use, compact design and upgraded with the latest chipset improving sensor performance and reliability. The innovative snap connector system eliminates the need to solder connections for the MyoWare 2 ecosystem. The MyoWare 2 Muscle Sensor measures muscle activity through the electric potential of the muscle, commonly referred to as surface electromyography (EMG or sEMG for short). When your brain tells your muscle to flex, it sends an electrical signal to your muscle to start recruiting motor units (the bundles of muscle fibers that generate the force behind your muscles).
The harder you flex, the more motor units are recruited to generate great muscle force. The greater the number of motor units, the more the electrical activity of your muscle increases. MyoWare 2 Muscle Sensor will analyze the filtered and rectified electrical activity of a muscle and output a signal (0-VIN volts, where VIN signifies the voltage of the power source) that represents how hard the muscle is being flexed. The MyoWare 2 Muscle Sensor builds upon its previous wearable design that allows you to attach biomedical sensor pads directly to the board itself, getting rid of those pesky cables.
This board includes a single-supply voltage of + 3.3V to +5V, three output modes, reverse polarity protect
