1. Introduction EMG detector is a bridge connects human body and electrical, the sensor gathers small muscle signal then process with 2th amplify and filter, the output signal can be recognized by Arduino. You can add this signal into your control system. Note: The sensor cannot be used for medical purposes. In standby mode, the output voltage is 1.5V. When detect muscle active, the output signal rise up, the maximum voltage is 3.3V. You can use this sensor in 3.3V or 5V system.
2. Features Grove Compatible 3.5mm Connector 6 Disposable Surface Electrodes Power supply voltage: 3.
3. Interface function J2: grove interface, connect to analog I/O; J1: EMG Disposable Surface Electrodes connector. U1: INA331IDGKT, difference amplifier. U2, U3: OPA333, Zero drift amplifier.
4. Demonstration This demonstration will show you how to use Grove - LCD RGB Backlight, we need a Seeeduino V3.0, a Grove - LED Bar and Grove - Base Shield. 4.1 Hardware Installation Plug Grove - Base Shield to Seeeduino, then connect Grove - LED Bar to D8, connect Grove - EMG Sensor to A0. Finally, tack the three electrodes to your muscle, and keep a distance between each electrodes. 4.2 Download Code and Upload You can download the demo code in github, click here, then extract it to anywhere.
4.3 Move When finish downloading demo code, it'll take about 5s to initialize, you should keep static when initializing. You can see that when initializing, the Led Bar will go form level 10 to level 0. When Led Bar All off, you can move now. When you are moving, you can find that the level of Led Bar will change.
