DFRobot Gravity: Analog EMG Sensor by OYMotion

This EMG sensor is launched by the cooperation of DFRobot and OYMotion, which can detect sEMG to reflect muscle and neural activities of humans. This sensor integrates a filtering circuit and an 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 depends on the intensity of muscle activities. The output signal waveform indicates the muscle activity and contributes to analyzing and researching 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 that can provide high-quality signal collection and it is easy to use. Only simple preparations are needed to apply the module for either static or dynamic areas. The dry electrode is applied to the module and good quality signals are available even without conductive gel.
