DFRobot Gravity - analogue EMG sensor, electromyograph -OYMotio.n

Index: DFR-10833 EAN: 6959420912780

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.

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.

Attention!

  • supply voltage is from 3.3 V to 5.5 V
  • the supply current should not be less than 20 mA

It gives a very consistent signal . I tested with FFT and the reliability is very high, you just place the electrodes on the same area ( with a reasonable margin of tolerance) and they work giving the same signal range. I can distinguish very well the flexion and extension of the wrist muscles.
