Yo guys..
can anyone help me/ advice me to this problem in my project?
i need to detect a person going out of a room. Yes, only out and not in.
what kinda sensor/module i can use and it must be small enough to attach at the door or ...?
Also if i want it to transmit wireless to my laptop.
Recently i just do some research on touch switch which might work as it could be attached to the door as the person is going to lock the door, he must touch it which send a signal to my laptop via wire.
how can i do it? is it possible?
Any suggestion/ help would be appreciated.
