EMG detector is a bridge that connects the human body to electronics. The sensor processes small muscle signals with 2th amplify and filter with an output signal recognizable by microprocessors like Arduino.
Note: The sensor cannot be used for medical purposes.
In standby mode, the output voltage is 1.5V. When muscle activity is detected, the output signal rises to a maximum voltage of 3.3V. You can use this sensor in 3.3V or 5V system.
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.
