Alarm system


hello everyone.
Is it possible to build an alarm system with a siren and RFID keys with no Arduino, only using 5 PIR detectors a raspberry pi a Rfid Rc522 module, and build in speakers output? has everyone ever tried? thank you!


why you want to use 5 PIR sensor?
first, add a RC522 to raspberry and get it working
once you are good with it, use to send data of PIR and RFID to cayenne and also add the code to play audio through the speaker.
