making a sensor door.
hey all,
I would like any information about every type of sensor doors, as i need one for a model house i am building. It would be helpful if you include how dificult the sensor door your explaining is, because the sensor door isnt the bulk of my project and i would like to keep it simple. I would also like it to sound a door bell when it opens if possible. and ideally have some type of locking (so when your out people cant just walk in) thx heaps in advance :wink:

The simplest would be one of those magnetic sensor ones, where there is a magnet on a side of the door and on the door frame there is a sensor that is triggered by the magnet, not sure if it's just a switch that gets attracted by the magnet or a hall sensor or somethin, but you could no doubt find one at home depot or lowes

Have you looked into RFID? I don't know too much about it, myself, just enough to think it may, for you. You give a tag to each person (or whatever) you want the door to open for, and that is when it opens.

a ir tx,rx combo is placed above the door. so when a person comes near , ir reflects back ,which is detected by the receiver and door openes. after a timeout period (say 20sec) , the door will be automaticaly closed. the rfid system is good and effective, but i feel it would be a more complex than this. |
