Description
The EMG sensor was created through the cooperation of DFRobot and OYMotion. EMG - electromyograph, sensor of electric activity of muscles and peripheral nerves of human. This sensor is a combination of a filtering and amplification chain. It strengthens the minimum value of sEMG in the range of ± 1.5 V 1,000 times and reduces the noise level via the differential input and analog filtering circuit. The output signal is analog, which consumes 1.5 V as the referencevoltage. The output voltage ranges from 0 V to 3 V. The signal's strength depends on the level of activity of the muscles. The waveform of the output signal indicates muscle activity, analyzes, and explores the sEMG. It is compatible withArduino, the supply voltage is from 3.3 V to 5.5 V.
The scheme of disconnecting the EMG sensor from Arduino
Sensor is easy to use, dry electrodes were mounted on a module, good signal quality is ensured without having to use a conductive gel. Measurements with the EMGsensor are non-invasive, comfortable and they can be used in interaction human-computer.
