Modeling & Testing of Automatic Pneumatic Sliding Door Using Sensors & Controllers

to automate the mechanism of door operation using Pneumatic, Arduino microcontroller and infrared sensor technology. The methodology applied in the project is divided into three parts, firstly designing and fabrication of the door with the calculated dimensions, secondly, developing a program on the Arduino for door operation and thirdly, interfacing the different components to work together in a cohesive manner. When an object comes in or goes out of the range of the sensor, a signal is sent to the Arduino which controls the electro-pneumatic circuit to open or close the door. The significance of this system is automation of the door which can be customized according to the industrial, commercial or domestic requirements. Based on the results obtained a small prototype was designed and a suitable code was developed taking into account the ambient light condition
