Wearable design for easy integrationSingle power supply operation from +2.9 V to +5.7 VReverse polarity protection to prevent damageTwo output modes: EMG envelope and original EMGExpandable with additional shieldsThe MyoWare Muscle Sensor is an advanced electromyography (EMG) device designed by Advancer Technologies. This compact sensor simplifies the process of measuring muscle activity by filtering and rectifying the electrical activity of muscles. It outputs a voltage ranging from 0 to Vcc (power supply voltage), depending on the muscle's activity. The sensor's latest version boasts a wearable design, eliminating the need for cumbersome cables by allowing direct connection to the sensor board. It operates on a single power supply ranging from +3.1 V to +5 V and includes features like RAW EMG output, an LED indicator, and an On/Off switch. Additionally, various shields are available to enhance its versatility and functionality.Color: As ShownMaterial: PCBPackage Contents:1*moduleOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
