Will my roller shutter sensors work?


i'm interested buying the konnected board and i'm wondering if the wired sensor for my roller shutter will work.
I'm asking this because the sensor pulses are very fast (i.e. with a standard multimeter is not possible to read hi and low values)

If will work, will be possible to setup the alarm to count n pulses in a certain window time before trigger the alarm (to avoid false alarms)

thank you
