Connecting the MyoWare Muscle Sensor to battery power allows for a cleaner signal while also eliminating the possibility of creating a dangerous current path to the power grid.\u003c\/p\u003e\n\u003cp\u003eOne thing to note is that due to the size of the batteries, the remote cable header on the MyoWare Muscle Sensor can’t be passed through. If you need access to these connections, this Power Shield will need to be stacked above the board(s) that need access.\u003c\/p\u003e\n\u003cp\u003eThe \u003ca href=\"\/en-eu\/products\/myoware-muscle-sensor\" target=\"_blank\"\u003eMyoWare Muscle Sensor\u003c\/a\u003e, that this shield attaches to, 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 the amount of activity in the selected muscle, where Vs signifies the voltage of the power source.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e The MyoWare Power Shield and the \u003ca href=\"\/en-eu\/products\/myoware-led-shield\" target=\"_blank\"\u003eMyoWare LED Shield\u003c\/a\u003e both provide power, but at slightly different voltages.
