Description
The sensor enables the control of electronic devices by means of bioelectrical signals generated by human muscles (EMG). The set consists of a main board, wires and six electrodes adapted to be placed on the skin. The output is an analogue signal, which can be read by any microcontroller with an analogue-digital converter, e.g. Arduino.

The device measures the electrical potential generated by the muscles. The signal is then amplified and transmitted in an analogue form to the main device. This examination in medicine is calledelectromyography(EMG) and is used to diagnose diseases of the peripheral nervous system.
Connection
The module shall be supplied with a symmetrical voltage between ± 3 V and ± 30 V, connecting a negative value to the -Vs pin, a positive value to +Vs. Two9 V batteriescan be used for this purpose. An example of how to create such a power supply can be found in themanual.
The output is an analogue voltage signal, proportional to the measured muscle activity. Its amplitude is in the range from 0 to Vs (supply voltage). This means that the sensor can be operated by any microcontroller with an analogue-to-digital converter.
