Hello Ijos,
Both the IOCore and CueCore can be triggered via digital signals. Note that the CueCore can't be triggered by any analog signals , which is possible with the IOCore. I don't have any experience the the sensors themselves, so I can't give you any advice on them. Before you use any of them, please do check for maximum voltage requirements, since to high voltages can damage your CueCore or IOCore devices.
Good luck and best regards,
Jurrien
