DFRobot Gravity EMG sensor OYMotion collects muscle EMG signals compatible with Ard

Notice:

1. The power supply voltage is between 3.3~5.5V, the power supply current is not less than 20mA, and the ripple and other noises are small. A regulated DC voltage is recommended.

2. The effective spectrum range of the muscle signal is 20Hz to 500Hz. It is recommended to use an analog-to-digital converter (ADC) with a resolution of not less than 8bit and an effective sampling frequency of not less than 1KHz for sampling and digitization, so as to retain as much original information as possible.

3. The matching metal dry electrode pads are used, and the electrode pads need to be kept in the same direction as the muscles.

4. This product is not a professional medical instrument and cannot be used as an auxiliary accessory for diagnosis.

characteristic:

Dry electrode probe, no conductive gel required, easy to use
Differential input, high common mode ratio, can effectively suppress noise interference
low power design
Single power supply
