You can indeed disconnect the LUX component, and connect another component capable of producing a digital or analog signal to that channel.
The digital input ports also allow you to synchronously record data from external components such as a switch for example.
Note however that, for the time being
, the firmware on the device is non-programmable, and it cannot be configured to respond to such signals.
To have "conditional" data recording, you have to either adapt the existing or create your own custom software to detect the trigger from the external component and start / stop data recording on a base station (e.g. computer or a smartphone).
If you'd like to have an autonomous system for data logging, the BITalino control logic needs to be on another component (e.g. Arduino or Raspberry Pi).
