Fingerprint Sensor Switch
The fingerprint-readout function is widely used in high-tech devices such as notebooks, advanced keyboards, and automated access control, but it is quite rare to find it on the market as a stand-alone device. This project fills this gap with a versatile circuit that is simple to build.
The goal of this project was to experiment with a biometric fingerprint sensor and to realize a stand-alone module that would act as a fingerprint-controlled switch, without the need for an interface with a personal computer. The output of the module can be easily connected to common electrical load control circuits, such as opto-isolators, MOSFETs, relays, as well as to other digital or analogue circuits.
