How does it determine the state of the door? Is it a beam sensor, switch lever, or just a tilt sensor?

It's a tilt. When the door i open (sensor flat) it blinks red for open. When door is down (sensor up and down) it blinks green for closed.

It's a tilt sensor. When installed on the top panel of the door, as the sensor moves from vertical, the receiver turns to red. In the vertical plane, the receiver shows green. It changes at approximately 20 degrees from vertical.

I have not cracked the case, but it does not rattle. If it is a tilt switch I think I should be able to make it activate by swishing it sideways and I can't. Pure silicon accelerometers and position sensors are super cheap, so I'm guessing that it is one of the two.

As per the other answers, I assume it is a tilt sensor in the transmitter that you attach near the top of the garage door.

This is a push switch. You instal the light on the hinge side, the switch facing the door. When door is closed, the door will push the switch to turn off the light. When door is open, the switch is loose and light is on. Very smart design - just like the light in a refrigrator.

You guys are really missing something simple. The garage door opener knows where it is because it has an encoder inside the unit that counts how many times it rotates past an electronic eye. It know the direction it is moving as well. So when you close it, it starts at 0 rotations and when you open it, it knows it takes 700 (pick a number) rotations to reach full open. Rinse and repeat. You guys crack me up with having to install it while the door is closed. These can be adjusted slightly (probably a foot either way) with the side knobs but not infinitely. How did you think the garage door opener knew when to stop when it was open, or when to stop before slamming into the ground? You guys are really missing something simple.

You could definitely use it to see when motion occurs in your mailbox (i.e. someone putting mail in or taking it out. You won't be able to see if the door is "technically" open or closed unless you use the light sensor built in to the unit. Additionally, you'll want to make sure the unit is close enough to your house for the sensor to communicate with the rest of the sensors in your house.

The sensors don't matter, just match your old remote.Pay attention to the frequency of the remote. There are different frequencies for different doors even though the remotes look the same on the outside. Check the back of the remote or the door opener.

It uses a pin with a knob that you pull up and the device tilts down. Very easy and works well.

Jim, it will close the door automatically according to the setting you use. I use the 3 1/2 minute setting but you can go to 5 minutes on up. It connects in two places ... the main box with the settings, etc gets attached to a wall next to or near your existing switches to open and close the door and the sensor gets attached to the rail upon which the door moves. Hope this helps, I love this product as does my neighbor.

The little door can stay on or off. If its off the detection angle will become wider causing the unit to be tripped at a wider peripheral.

It does have the switch for the door sensor built in. If the switch is the problem then it might fix it.

it's an actuator switch designed to unlock all four doors. It only works on the driver's door.

I'm surprised no one has actually figured this out yet and written this tip to help others figure out the tilt. You know how you pull on the handle to make the chair go up and down (the pneumatic lift)? Well, you just have to pull that bar out for tilt, and push it in for lock position. The knob is only for tension. Pull out the bar!

You have to turn the button. I like this feature since it's easy to tell if the door is locked with out opening the door.

It is possible. Try moving the magnet around all sides of the door sensor and see if you can get it to show as closed. You may also want to delete and then add the sensor back to the panel.

It has a pin that allow you to tilt the rack and open the door without removing the entire rack. Keep in mind you still have to deal with it in the way.

It is wired to the opener. It is wired to the same ports as the reverse sensors. It is very simple and the instructions are easy to follow.

Not sure...but as a suggestion your wasting your money if using it as a door sensor...

This is a door or window sensor. It is not stand alone it was added to my existing system.
