For my first Raspberry Pi project i'd like to do some some of IR Door Security (sort of security - basically my landlord is conducting house viewings at anytime and when i'm not in i'd like to know whats going on).
The idea is to have an infrared transmitter attached to the door and the receiver attached to the frame. When the door is opened this connection will be broken. From there i'd like to do various things, such as record from a webcam and send an email to notify me that my door's been opened. and vice-versa for closing the door. (and yes i understand that if they open the door and close it behind them it counters the security but i don't see a way around this).
So my question is how to i get started?
- What hardware do i need?
- Any hints on how to set it up?
- What software is needed and what language is suitable for this?
For me the hardest part is always starting, as soon as i know where to go i'm fine and enjoy experimenting and playing with various techniques. Any help is appreciated. Thank you.
