Add 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 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 analyze 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.

Pinout & usage notes
Check the supported input voltage before wiring so the module matches your controller and power source. For analog readings, use a stable reference and keep wiring short when possible for cleaner signals. If you are using Gravity connectors, align the plug correctly and avoid forcing the cable into the wrong header.
