Biosensor prototype for scientific research and CE certification

all315:
Thank you for the answer.

I don't want to use an RF module in my setup. I want to use the following setup:

  • Arduino controller board (CE certified)
  • EMG sensor (CE certified)
  • Vibrating motor (CE certified)

I can use them separately and simply connect them together with connectors, or I can put them all together in a box.

Have I to selfcertify this system in this case?

Yes, in theory at least, since its the finished article that needs to be certified, not the component parts.
