DFRobot Gravity OYMotion EMG Analog Muscle Sensor nodemcu v2 you need to buy moreAdd Reliable EMG Analog Sensor OYMotion Gravity Sensing to Your Next Build This EMG sensor is launched by the cooperation of DFRobot and OYMotion, which can detect sEMG to reflect muscle and neural activities of human. 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
