Senior Project-Help/Input

Senior design project overview:

Timeline ~ 8months

My design: I’ve decided to come up with an autonomous garage door opener system. The premise is quite simple. Even though people have a simple button they can click to open the door, sometimes (I know myself) can fumble through the car to find it, if it’s not hanging on the visor. So, how about a system where when you leave your driveway there are sensors that detect your vehicle leaving and in return will automatically close the door for you. Same idea when you return home, sensors know the car is entering the driveway and will automatically open the garage door. The system should/would be smart enough to already know that if you do return home and your door is already open, that it won’t shut the door (current state).

I’m just not sure how to get data to some type of receiver within the car after (I’m thinking a laser sensor) is tripped. I know they have RFID Bluetooth but I do not want this system being tied to a cell phone. Reason being is that if someone goes to get mail or comes close to the sensor at the end of the driveway we do not want garage doors opening and closing. So, I was thinking of a laser system that when tripped (at the end of the driveway), is triggered and goes out to find a tag (?) from the device sitting within the car (low power, runs on battery perhaps–Active RFID(?). From there, it’s verified, and relays the information back to the system within the garage. Problem is, I’m not sure if there are any devices/modules that will transmit like this.

Any input, both good and bad is welcomed. I’m all ears. Any help with what type of devices would be able to tie together. I’m thinking of an Arduino for the micro withing the garage, I do have an MSP430 here as well. I think the IDE for the Arduino is a little easier to use. My hurdle is that initial entrance into the driveway that verifies it’s the right car, to open the correct door, and then relay it back. Of course, all data needs to be sent over the air.

Thank you!

How is this any better than the existing system … where “I” pull into my driveway and push the button to open my garage door ? That it’s all automatic ? OK, but what of security. I may be counting on my garage door to be as secure as my other (lockable) doors. Any answer you may come up with has to address this point as well.

As to your idea … if the car already has a toll transponder, why not use that ? If not, why not require them to have the equivalent (a form of active RFID) ? Have the garage interrogate the local environment every X secs for an “allowed” car (or person) and open the door if not already open. IOW why bother with a laser system or even a PIR system ?

I am going the Active RFID route. It’s a senior project, gives us a chance to explore different possibilities with technologies in hardware/software. Thought the idea was decent so I’m running with it.

But hey, thanks for your input, I did say good or bad.

there are auto-door-closing product on the market. They risk legal liability if automation closes the door and causes injury or damage, despite the safety beams.
