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?????
Wait a minute - you do have multiple beams, don't you?
How about adding a movement detector to override the beams?
