Frequently Asked Questions

Significant changes in heart rate, like from exercise or stress, will directly impact the gate and envelope timings, making consistent patterns challenging.
Yes, external electrical noise and movement can affect the signal; careful placement and shielding might be needed for cleaner results.
While designed for the included clip sensor, the module accepts a standard sensor input, allowing experimentation with alternative biofeedback sources.
