It's interesting because Wiegand readers are widely spread in access control systems, and they are readily and quite cheaply available on the net. The good news is that we now have a solution, using a simple Yocto-Serial.

A connected smoke detector

By mvuilleu, in Measures and DIY, april 28,2017.

Although we don't explicitly have a smoke detector in our product catalogue, we recently started offering a product which can be used for this: the Yocto-RangeFinder. Indeed, this sensor uses exactly the same principle for its main feature (distance measurement) and can therefore easily be used as USB smoke detector, or even as a networked smoke detector.
