Having garage door sensors not only helps the door work accurately when it opens and closes, but it also helps reduce the chances of someone becoming trapped under the door as it shuts. In the past this was a real risk, but now that there are proper sensors for garage doors, there’s less of a chance of this happening. People are safer and more protected, and a lot of garage doors are also hooked into home automation and security systems, too. That makes them work better and keeps them safer, but can also make them more vulnerable to glitches — that’s why it’s more important than ever that the garage door sensor height is accurate.


There are several things to consider with the sensors, too, including:

  • who is installing them
  • what kinds of sensors they are
  • how long they’ve been in use.

Older sensors aren’t going to work as well or be as accurate, and they may need to be replaced so they can have a higher level of functionality. It’s also possible that older sensors will have been placed incorrectly, so they might have to be moved when replacing them. It’s all worth considering for a homeowner who wants to be sure to get the right garage door sensor height.

Choosing the Right Garage Door Sensor

The best garage door sensor is the one that’s affordable and reliable. It needs to work properly, or there’s no point in having it available. When a sensor can’t be trusted the door may not work the right way, and it’s also possible that someone will get trapped underneath it or seriously injured by it. This doesn’t happen too much anymore, but it can and does still occur in some cases.

When working with a company that’s going to install the sensors, or when buying the sensors to install them in a DIY manner, any homeowner will want to be sure to get the right thing and know what the rules are about it.

That reduces the chances that the sensors won’t be installed properly, and that can lower the level of risk the homeowner has, as well. Improperly placed sensors can even be an opportunity for a lawsuit or a homeowner’s insurance claim, so all of that has to be properly addressed, as well. That way there will be safety and security, but also a higher level of peace of mind.

Paying Close Attention to Sensor Height

As a general rule, garage door sensors should be mounted not more than six inches above the floor. That’s because they might not trigger properly otherwise, and people or animals could get trapped under the door as it closes. The object under the door needs to break the sensor’s infrared beam in order for the sensor to work. If the sensors are too high up, a person or small animal in that spot won’t break the beam — so the door will continue to close until it reaches contact with the floor. With a security system that’s tied to the sensors, and proper sensor placement, homeowners make their garage doors much safer.


How a Security System Affects Sensor Options

Not everyone who has garage door sensors has a security system that they’re tied to. But for those that do, there may be only certain kinds of sensors that can be installed. These are usually sensors that work with smart home automation, in order to make sure the entire house works properly together. With that in mind, also choose a security company that’s committed to working with automation and a homeowner’s needs, to get the most value.
