In the simplest terms, door sensors let you know when someone has opened a door. By far, the most common type of door sensor is the contact sensor, which uses a magnet to control a circuit that triggers an alert or alarm. A second type, however, involves depressing a switch to accomplish the same basic function. Many homeowners use door sensors to protect entrances, but sensors work on other types of doors, as well. In fact, they are so versatile that they are becoming one of the most popular activity triggers in smart home design.

  1.  Difference between fixed code and rolling code remote   Fixed code: It means that the code will not be changed every time when it is sent out. This kind of remote control   chip  is easier to copy . Rolling code:   It refers to the code that is sent out each time is different, through a series of algorithms to complete the function of rolling. This type of chip copy is more difficult, you can complete the copy work by shifting, or the remote control that has been cracked . 2.  Which kind of remote OSSDEN uses? For most of our gate motors, we use rolling code remote. When you lose remotes, please delete the previous remote by pressing the learning button on the gate motor control board for about 10 seconds, then learn the remotes again, the previous losing remote can ’ t open the gate, which is convenient and safe for customer. 3.  How to learn a remote when installing a gate opener ? Remote learning method: Press the learning button on the c...

  The  automatic door  opening systems are used in commercial buildings, shopping malls, theatres, etc. These systems are used to open the door when a person comes near to the entrance of the door and closes it after he moves away from the door or after entering into the door. There are various kinds of sensors are available in the market to make such types of systems such as Radar sensors, PIR sensors, Infrared sensors, and Laser sensors, etc. This project uses a PIR sensor to open or close the door automatically which senses the infrared energy produced by the human body. When someone approaches the door, the IR energy sensed by the PIR sensor changes and activates the sensor to open and close the door automatically. Further, the signal sent to the microcontroller to control the door. You might have seen Automatic Door Opener Systems at shopping malls, cinemas, hospitals etc. where, as soon as a person approaches the door (at about 2 or 3 feet), the door automatically s...

The reason why the automatic door can operate freely is mainly due to the sensor information of the door opening signal, which shows the nature of the door opening signal for the automatic door. There are two main types of door opening signals for automatic doors in the current market: The first type-microwave radar. This kind of door opening signal is a response to the displacement of the object, so the reaction speed is fast, and it is suitable for places where people with normal walking speed pass. Its characteristic is that once the people near the door do not want to go out and stand still, the radar will no longer respond. , The automatic door will be closed, which has a certain protective effect on the door machine. The second type-infrared sensor. This kind of door opening signal responds to the existence of objects, no matter whether the person moves or not, as long as it is within the scanning range of the sensor, it will respond and send out a contact signal. However, the d...
