Garage door controller/checker



  • Time to think bout a new project.

    The comming months I am building a new garage . I want to controll and check the garage via my vera3. Option is to buy a universal sensor and fibaro relais , but why not with my sensor stuff?

    What does it need to do:
    -open en close the garage >> via a relais what closes the contacts momentarely ( 1 or 2 seconds)
    -checks if the garage is open , closed or in transit: via reed switches ; one on the open opsition and one on the closed position. >> sketch will be door sensor/siwtch.
    -sensor to check if the entrance/garage door is clear to close , or emergency stop when "the beam" is interupted. >> No idea what this is called , but I guess the sketch will be like the "door sensor/ switch" .
    -temperature sensor. >> ( Dallas DS18B20).

    What do you guys think? Is this possible? , on an arduino nano 3x reed switches and a temperature sensor?

    I allready have a sketch here for 1 temperature sensor and 1 reed switch:

    This one has not the IRQ pin on the radio connected , on pin 2 is a reed sensor. Can this sketch easily be adapted for 3 reedswitches and also have a relais attached?

    One of the reed switches needs to be "inversed", when the contact is closed, it actually has to say "garage open".

    Thanks,

    I made a garagedoor node some time ago maybe you can find my post about it usefull.

    http://forum.micasaverde.com/index.php/topic,22334.0.html

    here is the current sketch I use.

  • Awesome Kortoma,

    That is a very good start. Thanks for this.
    When I read through the sketch ( and what I understand from it), it is not possible to have the reed switches 1 "normal" and another one "inversed"? it is both switches have to act the same?

    Will it be difficult to add another switch to act as a "beam" to sense if the door is clear to close it?

    Can a temperature sensor be added?

    Thanks,
    Cor



  • I built this controller using the above code (plus atshasoft signing), and it works great when connected to computer's usb port, but doesn't work when connected to either a USB power adapter, a 12v input on the VIN pin, or 5V on the 5V pin. I'm not sure what could be the issue here. I'm using an arduino nano.

    EDIT:
    Ignore my stupidity. When you hook up the radio to the 5V instead of the 3.3v output only a PC has a low enough voltage for the (somehow not fried) radio to work. Connecting to the 3v3 works...

    somehow not fried

    lucky!

    😰



  • how about adding an ultrasonic sensor to tell if your car is IN the garage or not?
