How Garage Door Sensors Work
Garage door sensors play a crucial role in ensuring the safety and functionality of your garage door. These sensors use advanced technology to detect obstructions and prevent accidents or damage to your vehicle or property.
Understanding how garage door sensors work can help you appreciate their importance and make informed decisions when it comes to maintaining and troubleshooting them.
The Sensor Types
There are two main types of garage door sensors: the photoelectric sensors and the mechanical sensors. Photoelectric sensors, also known as optical sensors, work by emitting an invisible beam of light across the garage door opening.
When an object interrupts the beam, the sensors detect the obstruction and signal the door to stop closing or reverse its direction. Mechanical sensors, on the other hand, use physical contact to detect obstructions.
These sensors are typically located at the base of the garage door and will stop the door from closing if they encounter resistance.
How They Detect Obstructions
Photoelectric sensors utilize an infrared beam of light that is emitted by one sensor and received by the other. When the beam is uninterrupted, it means that the garage door opening is clear. If the beam is broken, indicating an obstruction, the sensors send a signal to the garage door opener to halt the closing or reverse its direction.
Mechanical sensors work by detecting changes in pressure or resistance. When the garage door encounters an object or obstacle, the sensors sense the resistance and trigger the door to stop and reverse.
Common Placement
The placement of garage door sensors is crucial for their effective operation. Photoelectric sensors are typically installed on each side of the garage door, a few inches above the ground. This allows the infrared beam to span across the opening.
Mechanical sensors, on the other hand, are installed at the base of the garage door, near the floor. They are strategically positioned to detect any obstruction that may be encountered while closing the door.
It is important to ensure that the sensors are properly aligned and free from any dirt or debris that could interfere with their functionality.
Understanding how garage door sensors work and their different types can help you troubleshoot any issues that may arise. Regular maintenance and cleaning of the sensors are essential to ensure their proper functioning.
If you experience any problems with your garage door sensors, it is recommended to consult a professional technician who can diagnose and resolve the issue promptly.
