Some people has the potential to forget some of thier stuff before they leave thier houses, For example, wallet, keys chain or thier phones. So, this project is here to make your life easier by remind you to take your stuff that you have left in your house by mistake.
How this project going to function
One motion sensor with a RFID will be in a space in your house and the other one will be held next to the front door of your house. You will put your stuff on the RFID, whenever you leave your stuff in there for example, wallet, phone and glasses the other photon will be activated whenever you pass the photon of the motion sensor, but if you take your stuff out of the RFID and leave your house, the photon will not activate the buzzer in the other photon.
Here is the photon with the buzzer and the motion sensor
Photon with the RFID card. Here the photon is conected to the motion sensor.
Here is another figure of the photon with the RFID card and the motion sensor.
Here is the circuit diagram of the secod photon that is responsible of the alerting part.
Here is the first photon with the RFID tag reader and motion sensor connected to it.
The RFID tag reader and the motion sensor. It reads the RFID tag when there is motion around it.
This graph showing the time that the motion sensor detected any motion, also it shows when its turn off or detected nothing; so here the yellow graph shows the RFID detection and the blue one showing other one.
