Your garage door is a vital part of your home, providing security and convenience. But what happens if that convenience turns into a safety hazard? Garage door sensors are a crucial safety feature that prevents the door from closing on people, pets, or objects in its path.
In this blog post, brought to you by Emu Garage Door, we'll delve into the world of garage door sensors, explaining how they work, different types, and troubleshooting tips. Understanding Garage Door Sensors
Garage door sensors, or photo-eyes or safety beams, are small devices mounted on either side of your garage door, near the floor. They work together to create an invisible tripwire using infrared technology
The Importance of Garage Door Sensors
Imagine this: you're pulling your car out of the garage, and the door starts closing before you're fully clear. Without garage door sensors, a serious injury could occur. These sensors prevent the door from closing on any object in its path, protecting children, pets, vehicles, and anything else you might have stored in your garage.
How Garage Door Sensors Work
Garage door sensors utilize infrared technology to create an invisible tripwire. Two units are installed on either side of the door, typically near the floor. One sensor transmits a beam of infrared light, and the other receives it. As long as this beam remains uninterrupted, the door functions normally. However, if the beam is broken by an object in the doorway, the signal is disrupted, and the door immediately reverses its direction and opens back up.
Different Types of Garage Door Sensors
The most common type uses Garage Door Sensor Infrared Photoelectric Sensors, Pressure Sensors, Carbon Dioxide Sensors
Infrared Photoelectric Sensors : These are the workhorses of garage door safety. They use an invisible infrared beam like a tripwire. A transmitter emits the beam across the opening, and a receiver on the opposite side detects it. If the beam gets interrupted by an object in the doorway, the receiver signals the door opener to stop and reverse.
Pressure Sensors: These sensors are installed along the bottom edge of the garage door. They contain pressure pads that detect resistance when the door comes into contact with an object. If the pressure sensor is activated, it triggers the door to reverse course, preventing it from closing on anything.
Carbon Dioxide Sensors: These are not as widely used but provide an extra layer of safety. They are designed to monitor carbon dioxide levels in your garage. If the CO2 level rises significantly, it could indicate a person or pet trapped in a closed garage with the car running. The sensor would then trigger the door to open, providing an escape route.
Troubleshooting Garage Door Sensor Issues
If your garage door isn't closing properly, the culprit might be the sensors. Here are 3 common issues Misalignment, Dirty Lenses, Loose Wiring
Maintaining Your Garage Door Sensors
Regular Inspection: Visually inspect the sensors for damage or dirt build-up.
Keep the Area Clear: Avoid placing objects near the sensors that could obstruct the beam.
Professional Maintenance: Consider scheduling professional maintenance for your garage door opener every 1-2 years. This often includes checking the sensors.
