Six Channel EMG Muscle Sensor Module Controller Detects Muscle Activity with Arduino Uno Development Board Smart Automation Kit
Description

The six channels EMG module consists of a front-end analogue circuit for acquisition and a back-end digital signal filtering process. The front-end acquisition circuitry acquires the electrical signals from the human arm or leg through channels 1 to 6, and then amplifies and filters the EMG signals through a series of signals; the middle-end can switch between Envelope Mode and RAW Mode output signals through SPDT switches; Envelope Mod uses envelope detector processing to obtain the EMG dynamic detector signals, and RAW Mode can The Envelope Mod uses envelope detector processing to obtain the EMG dynamic detector signal, the RAW Mode outputs the original EMG signal and the channel gain of the Envelope Mode and RAW Mode outputs can be adjusted via the blue and white potentiometers. An external single channel Audio Output Interface is also available to output the raw signal. This audio interface can be jumpered with a jumper cap to output the raw waveform of a channel, allowing the user to monitor and analyse the current EMG signal in real time with external instrumentation. The back-end uses the Arduino UNO development kit with the six-lead muscle module to collect the output signal from the middle end and control the LEDs to quickly reference the EMG signal intensity. The user can write their own Arduino code to extend the design, e.g. by controlling the six channels of output control pins based on the collected EMG signals, to achieve muscle control of stepper motors, gripper hands, light bars etc.
