Door Locking System With Using The Motion Sensor Essay

Door Locking System With Using The Motion Sensor - Essay Example Introduction It is indispensable that the evolution of the world has been accompanied with various technological developments to the extent that the world can longer do without them. There is always increasing need to make various changes to keep abreast with the demand of the society. As far as electronics is concerned, these developments are not disputable. The changing times have seen new materials discovered, and the application of such material to change the outlook of the environment has been enormous, needless to mention improved locking system of the door, safety and performance for sustainable development. One pivotal area that technology has found a lot of applicability is that pertaining to application revolving doors fitted with motion sensors. It is worth noting currently there are a number of door available as options to architects whenever they wish to design commercial, educational or public buildings. The doors range includes both manual, automatic and both manual an d automatic combined. One thing to content with is that the underlying needs are most likely the same for instance when considering ease of use, their effectiveness, or their safety for the user. Revolving doors first appeared in the market in a New York Restaurant way back in 1899 though it is said that the idea was conceived by the Philadelphia residents about ten years earlier. Today, revolving doors are quite relevant hence widely used. Basically, the revolving doors are made of a number of three to four panels often referred to as leaves or wings.
