Working Mechanism Of An Automatic Door Opener

Shopping malls, hospitals, commercial buildings have automatic doors. Have you ever thought about their working? An Automatic Door Opener opens when you stand in front of it and closes automatically. This technology has made the entrance of many buildings easy.

What Kinds Of Technologies Are Used In Making Them?

There are many technologies used to make automatic doors. Radar sensors, Arduino bases, PIR sensors, and infrared sensors are most readily system in such doors.

Working In the Arduino automatic door openers, motion-detecting sensors are used to open and close the door. The infrared energy released by the human body is detected by the PIR sensor and so the door function when someone approaches the door. The sensor changes when someone approaches the door and the Arduino UNO receives the signal accordingly.

PIR Sensor- A Brief Description Pyroelectric or IR motion sensors notices the change in heat and the output pin changes accordingly. Everything when heated emits some infrared rays. The PIR sensors specialty is that they can detect even small variation. So, when any human or object passes through the sensor range, some friction is produced between air and object which is detected by the PIR. There are some capacitors, resistors and other components that complete the PIR circuit. The pyroelectric sensor is divided into two parts and both halves remain in the same state when there is no motion. Both the parts can detect the level of infrared and when someone enters the automatic door, the infrared level of the first half becomes higher than the other and the output pin changes to high. The pyroelectric sensor has a Fresnel lens inside the array which is covered with a plastic cap. These lenses cover many ranges of infrared rays.

Get An Automatic Doors The PIR sensor senses the human motion and is specially designed to help the handicapped through the door. Kensington Automatic door openers are very beneficial in case of an emergency and work as a second manual door in such cases. Wheelchair and scooter users can now install such doors at home due to their economic nature. Moreover, the installation procedure is easy, and each proper unit can be installed in some time and you can enjoy this service for a lifetime. The automatic door opener providers have a big network and periodically come to check the operation of the system, and try to incorporate them the latest technologies in the door.
