Electromyography (EMG) Sensor
MYO v1.5

MYO v1.5 is an ultra-compact electromyography (EMG) sensor with high performance signal, designed according to the plug and play approach. This sensor provides the easiest way to turn your ideas into reality in the field of EMG research and development.

You can easily connect the MYO v1.5 sensor to the most popular microcontrollers such as Arduino, ESP32, STM32, etc. We provide libraries and examples for Arduino IDE that will help you to get started on using our sensor in your projects and make it much easier to bring your ideas to life. Our sensors is already being used by developers and researchers in such fields as EMG control systems for exoskeletons and prostheses, EMG research regarding physical activity, somnography and relaxation.

For visualization, analysis and signal processing we provide the Elemyo GUI – free open-source software for working with the sensor, based on Python. It allows to visualize EMG signal in real-time, record and replay it, set filters and envelope. Furthermore you can make any required additions, using Python.
