Myoelectric sensor MYO v1.4
(for registration EMG signals)

MYO v1.4 is a compact EMG sensor, designed for registration and measurement body biopotentials, such as an electromyogram and an electrocardiogram. It has an adjustable signal gain. We provide software and free libraries for visualisation EMG signals.

MYO v1.4 is a ready for use compact myoelectric sensor, designed for registration and measurement muscle and heart activity.

Very easy to use with such microcontrollers as Arduino, STM32 and Teensy. To receive a signal, it is enough to power the device with a voltage of 5V (no more than 5.5V) and connect the output signal to a ADC, all step-by-step instructions are described in a datasheet of the sensor.

We provide free libraries for using MYO v1.4 with Arduino to help you implement your project ideas regarding muscle activity, such as EMG control systems or EMG research tasks.

Also we provide sketches and software for EMG signal visualisation by Python and Matlab.
