Dear friends welcome to another tutorial! Today we are going to build an interesting Arduino project which is using a fingerprint sensor ...

Yes, these photocells are similar than the ones I am using in this project. I recomentd that you choose 12V powered in order to use the same power supply that you are using for the main control unit (Arduino, Oled display, relays, ...). Normally these devices offer a NO or NC connection, so you can choose what you preffer. I prefer to use NC connection because I think is safer (if the wire or connector brakes then the door will stop, otherwise it will not detect nothing and this could be dangerous).
On the other hand, this kind of photocells has a drawback. They need to be powered for both units, the emitter and the receiver (each one at each end of the door travel). This could be a problem if you are not able to "cross" the door gap with power wires. If this is the case then you could use instead another sort of photocels that only one of the units are active and need the power supply. This is because one unit has embedded the emitter and the receiver and the other unit is a simply reflector (catadioptric disc).
I hope this helps.
Oui bien sûr. Vous pouvez utiliser Arduino UNO. J'ai utilisé Arduino NANO simplement parce que c'est moins cher et plus petit pour un montage dans la boîte.
Merci beaucoup pour votre commentaire. C'est une bonne simplification du circuit !!
