Hi all, i am making a project where i install infrared sensors on the doorway and when a person enters, it senses and the light switches on, and switches off when the person goes outside. it is working fine, except if 2 people come one after another the light switches off, how to tackle this problem?????
Well you'd better get debugging, then!
Apart from you, nobody can see your hardware; Apart from you, nobody can see your software; Apart from you, nobody can see what's actually happening in your system when these people go in & out.
Therefore, apart from you, nobody has any chance to debug your system - unless you provide a lot more information!
the problem is that the sensor trips and switches off the room lights even when person who has entered the room is still in the room bu another person has came in.
basically, it cannot tell difference between 1 extra person coming in the room or the person already in the room leaving the room.
Wait a minute - you do have multiple beams, don't you?
How about adding a movement detector to override the beams?
