Este blog not only offers an overall introduction of all types of garage door sensor, but also gives solutions of their common malfunctions.
What Are Garage Door Sensors?
Garage Door Sensors basically contains infrated photoelectric sensor, smart magnetic door senor and Remote WiFi Sensor. All of them organically made up an smart IoT garage door system to bring safety and convenience. Through the Internet of Things technology, these garage door sensors enable garage door status monitoring, remote control, and security alarms. Through centralized management on the mobile app, they can conveniently take care of the daily needs of users in the family garage.
Types of Garage Door Sensor
Infrated Photoelectric Sensor for Door-Caught Prevention
In daily household life, children and pets are often less safety conscious so they are more likely to be caught by a falling garage door. For this case, the infrated photoelectric sensor can prevent such accidents when adults are too busy to secure their children and pet. Además, sometimes we may misjudge whether the car is beyond the door when parking. Entonces, it can precisely help us check if we are crossing the line. This greatly prevent the garage door from scratching the crossing car.
Smart Magnetic Door Senor for Intrusion Alerts
When detecting illegal intrusion or abnormal conditions, it can trigger sound, light alarms and mobile app notifications. Además, via IoT network, it can connect to smart lights in the home. Por ejemplo, when the user comes home and opens the garage door, the lights in the home will turn on.
Remote WiFi garage Door Opener
With remote WiFi garage door opener, users can remotely control the opening and closing of the garage door in a mobile APP or web page anywhere. This means that when a user forgets to close the door or needs to open the door for someone they trust, he can do it in a fingertip. Even, with a smart home voice assistant on a smartphone or speaker, the garage door can open automatically when the user gives voice command.
How Does It Remotely Telecommunicate to the IoT Network?
Traditionally, the Infrated Photoelectric Sensor for door-to-caught Prevention does not communicate wirelessly directly. Instead, it is connected to the controller or microprocessor by wired means . Sin embargo, in some advanced OEM solutions, infrared photoelectric sensors can be used with gateways to enable wireless communication.
En contraste, the smart magnetic door senor for intrusion alerts can communicate directly through the built-in wireless communication module, after converting the electrical signal into a wireless signal. After receiving the wireless signal, the receiving end (such as a gateway, controller, or smartphone) parses the signal and followingly sends an alert. As for the remote WiFi sensor for door opening, its built-in WiFi module allows the wireless router to establish a connection to IoT network. When the smartphone app sends a signal of opening the door, the cloud server transmits the command to the door opener. De este modo, users can remotely open the door to the trusted people no matter they are in the car before the door or they are in the office.
How Does Garage Door Sensor Work?
In addition to the working principle of the communication module, the infrated photoelectric sensor and smart magnetic door senor both come with sensing modules, which play an important role in the operation of the devices.
The working principle of the infrated photoelectric sensor is mainly based on photoelectric effect and infrared detection technology. Por un lado, infrared transmitters emit infrared light at a certain frequency. The infrared receiver, on the other hand, is responsible for receiving infrared rays, which travel through space and may be reflected back by obstacles. When an object enters the range of the infrared beam, they will block the infrared beam. Por lo tanto, the infrared signal received by the receiver will be weakened or completely disappeared. Once this happens, the circuit will immediately trigger the alarm and stop the closing the garage door.
The smart magnetic garage door sensor is usually composed of two parts. There are the magnetic strip and the door magnetic body. The magnetic strip contains a permanent magnet that generates a constant magnetic field, while the door magnet body is a magnetic sensing element. Since the magnetic sensor is a device made of two elastic tongue reeds made of soft magnetic material encased in a glass tube, the tongue reeds are magnetized each other to make the circuit conductive when the magnetic field of the magnetic bar is close. Otherwise, the circuit is disconnected. Entonces, the sensor transmits the captured electrical signal to the control system. After receiving the signal, the control system will analyze and process it. If it is confirmed that it is an illegal intrusion, an alarm will be triggered and an alert message will be sent to the mobile APP.
What Are the Key Features of Garage Door Sensor?
Due to the above sensing working principle, the smart magnetic garage door sensor mainly features accurate feedback on the switching status of the garage door. Además, it is very durable because it is usually designed with protection and low power consumption. The infrated photoelectric sensor for door-caught prevention is known for its quick response. When it detects that there is an object approaching or passing through the detection area, it will quickly and timely send a signal to prevent the door from closing. Además, it has extremely low power consumption in the standby state, and only starts to work when detecting an object, thus achieving the purpose of energy saving and environmental protection. The remote WiFi sensor for door opening is marketed as remote control. No matter where users are, they can control the status of the garage door from their smartphone, tablet or other smart device, .
What Does the Flashing Light of My Garage Door Sensor Mean?
This problem is generally aimed at the Infrated Photoelectric Sensor for door-to-caught Prevention. If its indicator is blinking, it may be caused by the following reasons.
- The sensor may detect abnormal conditions, such as internal circuit failure, power instability, sensor occlusion or contamination. En este caso, the blinking light may be a warning signal from the system to prompt the user for inspection or maintenance.
- The sensor may alert the user by flashing lights when it detects an object.
- When the sensor is calibrated or set up, the light may flash in a specific pattern.
What Are Common Malfunctions of Garage Door Sensor?
- The optical path of the sensor transmitting and receiving infrared rays is blocked by dust, dirt, occluders, etc., causing the sensor to fail to detect objects normally.
- The light-emitting element or receiving element inside the sensor is damaged.
- The circuit part of the sensor is short-circuited and disconnected, resulting in abnormal signal transmission.
- The sensor installation position is too high, too low or deviates from the center line of the door body, resulting in the inability to effectively cover the moving area of the door body.
- The sensor’s sensitivity, response time and other parameters are improperly set, resulting in false positives or missing positives.
- When the strong natural light or artificial light source shines directly on the sensor, it will cause optical path interference and affect the detection accuracy.
- Extreme temperature or humidity conditions may cause deterioration in the performance of components inside the sensor, thus affecting the detection effect.
- The sensor power supply voltage is unstable or the power line is faulty, resulting in the sensor cannot work normally.
How Can We Fix These Problems?
Sensor Fault Repair
In order to repair the fault that the optical path is blocked, we can use a clean soft cloth or special cleaning tools to gently wipe the sensor surface to remove dust, dirt and other obstructions. Además, in daily life, we can regularly check whether the sensor light path is smooth.
Ensure that no other objects around the sensor block its optical path and keep the optical path unobstructed. Sin embargo, if the internal components of the sensor (such as infrared leds or photodiodes) are damaged, the maintenance will be a bit difficult. Because it is often necessary to replace the entire sensor or associated parts, this may require contacting the supplier for a replacement. If there is a circuit fault, we should check the circuit part of the sensor for short circuit and open circuit with the multimeter. Then repair it according to the specific situation.
Installation and Configuration Problem Solution
If the installation position is improper, we can re-evaluate the installation position of the sensor. En general, it should be installed on the center line of the door body movement area.
If the configuration of the sensor is wrong, we can enter the configuration interface of the sensor to check the sensitivity and response time parameters. This ensures that the sensor accurately detects the object and avoids false or missed alarms.
Remediation of external environmental effects
We try to avoid installing the sensor in an environment with strong light. O, we can install a hood to reduce light interference. Además, we should also check the light around the sensor regularly in our daily life to ensure that no strong light directly shines on the sensor. Similarmente, if the sensor stays in an extreme temperature and humidity environment, we can consider installing a protective cover to protect the sensor from environmental effects.
Power Problem Solution
We need to check whether the power line of the sensor is intact to ensure that the power supply voltage is stable. If the power line is faulty or the power supply voltage is unstable, it is necessary to repair or replace the power line in a timely manner.
Daily Maintenance to Ensure Its Lifespan
Cleaning and maintenance
We recommend regularly wiping dust and dirt on the sensor surface with a clean soft cloth. In order to further ensure smooth light path is smooth, we also need to ensure that there are no objects blocking the propagation of light.
Connection and Fixture
It is very useful to periodically check that the cable connection of the sensor is secure. If there is a bad cable connection, we should repair or replace the cable in time. Mientras tanto, don’t forget to make sure the sensor is securely installed and not loose or wobbly.
