Introduction
This EMG sensor is launched by DFRobot and OYMotion cooperation, which can reflect muscle and
neural activities of human by detecting sEMG.
This sensor integrates filtering circuit and amplified circuit. It amplifies minimal sEMG within ±1.5mV
1000 times and depresses noises (especially power frequency interference) by differential input and
analog filter circuit. The output signal is analog,which takes 1.5V as the reference voltage. The
output voltage range is 0~3.0V. The signal strength is depends on muscle activities. The output
signal waveform indicates the muscle activity and helps to analyse and research the sEMG.
Specifically, we can use Arduino as a controller to detect muscle activities, e.g. check whether the
muscle is tense; the muscle strength;etc.
This is an active induction sensor can provide high quality signal collection and it is easy to use.
Simple preparations are needed to apply the module to whether static or dynamic areas. Dry
electrode is applied to the module and good quality signal are available even without conductive gel.
Compared with disposable conductive gel needed by medical electrodes, it is more convenient to
use and has longer service life. Therefore, it is more suited to common users.
Measurements with an analog EMG sensor are noninvasive, convenient and this can be applied to
human-computer interactions. With the development of microcontrollers and integrated electric
circuits, EMG circuits and sensors have not just been applied to traditional medical muscle detection
researches but control systems.
