Anyway I can get a fingerprint scanner. Install it outside my door and have smartthings send me a notification if the incorrect fingerprint/no fingerprint is scanned upon entry?
There are numerous cheap fingerprint scanners that offer a normally open (NO) dry contact output… hook one of these up to a dry contact sensor and you have a smart scanner.
Sinething like this, hoooked up to a Fibaro Contact Sensor (dry contact terminals) would work nicely.
this is a good idea.
is this the dry contact sensor to use:
And how do we power it ? battery/AC/DC ?
That would work, it needs a 12v power supply, but I’ve found them to be a little unreliable.
I used to reccomend these:
But Fibaro discontinued them, maybe use something like this instead:
thanks. These are of course better since they work on battery. But how do you connect them to a dry contact fingerprint sensor ? (since they are closed box sensors with magnetic trigger, I don’t know how to connect them as a dry contact sensor ?)
According to the manual you can open the case and it has dry contact wiring terminals on the inside.
this is good. since it is battery operated, can I find a battery operated fingerprint sensor with dry contact ?
highly unlikely… needs a small computer inside to compare the prints, that’s a lot of power needed.
