SEN0240

SEN0240 is a Gravity analogue Electromyography(EMG) sensor cooperatively launched by DFRobot and OYMotion, and can reflect muscle and neural activities of human by detecting sEMG. 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 analogue filter circuit. The output signal is analogue which takes 1.5V as the reference voltage. The output voltage range is 0 to 3.0V. The signal strength depends on muscle activities. The output signal waveform indicates the muscle activity and helps to analyse and research the sEMG signals. 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 active induction sensor can provide high quality signal collection and it is easy to use.
