2015 3-lead Muscle / Electromyography Sensor for Microcontroller Applications MyoWare Muscle Sensor (AT-04-001) DATASHEET FEATURES NEW - Wearable Design NEW - Single Supply +2.9V to +5.7V Polarity reversal protection NEW - Two Output Modes EMG Envelope Raw EMG NEW - Expandable via Shields NEW - LED Indicators Specially Designed For Microcontrollers Adjustable Gain APPLICATIONS Video games Robotics Medical Devices Wearable/Mobile Electronics Prosthetics/Orthotics What is electromyography Measuring muscle activation via electric potential, referred to as electromyography (EMG), has traditionally been used for medical research and diagnosis of neuromuscular disorders. However, with the advent of ever shrinking yet more powerful microcontrollers and integrated circuits, EMG circuits and sensors have found their way into prosthetics, robotics and other control systems.

It is also acceptable to power the MCU with a battery via the USB or barrel ports. b) Battery powered sensor, Grid powered MCU with output isolation Note: Isolation amplifier and battery provide isolation between user and electrical grid. IC models are suggestions only. Isolation Amplifier (ISO124) www.AdvancerTechnologies.com EMAIL: support advancer.co RECOMMENDED (Note: Arduino and batteries not included. Arduino setup is only an example sensor will work with numerous other devices.)
