Working Mechanism Of An Automatic Door Opener

-

Shopping malls, hospitals, commercial buildings have automatic doors. Have you ever thought about their work? 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 notice the change in heat and the output pin changes accordingly. Everything when heated emits some infrared rays. The PIR sensor's specialty is that they can detect even small variations. 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 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 the latest technologies in the door.

Image
What is FOUP? The FOUP is defined as Front Opening Universal Pod, which is the exclusive plastic enclosure equipped for handling the silicon wafers in a safe environment. The other name of FOUP is the Front Opening Unified Pod. The primary purpose of this device is to allocate the wafers in the machines to increase the processing performance. In the mid-1990s, 3000mm FOUP was developed as the wafer processing tool. Many companies design their FOUPs in different color combos, and their product sizes also vary according to the brand. In addition, IC processing equipment and the FOUP can provide the nitrogen ecosystem to boost the device productivity. Previously, the engineers may only develop the 300mm FOUP with the detachable cassette to place the wafer in the right position. But now, 400 mm wafer FOUP load ports are also easily accessible from the robotics laboratory. It may allow the swapping of doors from front to bottom so that robot mechanisms can access the wafer from the FOU...

Silicon wafer is the main element in integrated circuits and is used in one-step production for moving firm substrates. Generally, the integrated circuit is a mixture of different electronic parts put together with silicon wafers placed on the main platform of semiconductor apparatuses. The wafer is finely cut for the semiconductor material so that it functions as the substrate over the wafer with microelectronic apparatuses incorporated. The silicon wafer stage used in cohesive circuits is used in contemporary society daily. Computers, smartphones, and other gadgets are completely reliant on these apparatuses. Semiconductors are examined many times before they are incorporated into the devices. Silicon wafers are used in sensors to gauge tire pressure and solar cells. The wafer’s primary function is soaking up the photons in sunlight to generate electricity. Researches on Silicon Wafers The silicon is used for producing superior silicon and other firm substrates for high-valu...

What is FOUP? The Front Opening Universal Pod or FOUP is the exclusive plastic enclosure used for handling the silicon wafers in a safe and secure environment. FOUP is also known by another name, Front Opening Unified Pod. The main purpose of this device is to designate the wafers in the machines for increasing the processing performance. FOUP opener is used to check for any abnormalities by opening the lid.  3000mm FOUP  was developed in the mid-1990s as the wafer processing tool. Many businesses design their FOUPs in various color combos, and the product sizes vary as per the brand. Also, FOUP, as well as IC processing equipment, can provide the nitrogen ecosystem for boosting the device productivity. Earlier, engineers were able to develop only the  300mm FOUP  with the detachable cassette, which was used to place the wafer in the right position. With the advancement in technology, 400 mm wafer FOUP load ports are easily accessible from the robotics labor...
