- Cat nail clippers with LED lightsGravity Analog EMG Sensor

• Sensor that can detect sEMG to reflect muscle and neural activities of human
• Spectrum range is 20Hz～500Hz
• Amplifies minimal sEMG within ±1.5mV 1000 times 
• Depresses noises by differential input and analog filter circuit
• Operating Voltage: +3.0V

This Gravity Analog EMG Sensor can detect sEMG to reflect muscle and neural activities of human. It 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. The output signal is analog, which takes 1.5V as the reference voltage.

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. Arduino can be used as a controller to detect muscle activities, e.g. check whether the muscle is tense; the muscle strength, etc.
