In the last two decades the various equipment’s are being changed to deposit thin film coatings. Previously, a typical coating machine which was completely manual or semiautomatic also required a highly skilled operator was used to produce consistent results. The increasing sophistication of the user translates to ever more demanding specifications for system performance; it is not unusual for customers to buy process expertise along with the machine. In this project an attempt has been made to examine the components and subsystems which are available for today’s thin film coating systems, highly tuned thin films, in terms of thickness, crystalline, porosity and optical properties, can be fabricated on different substrates using the sol-gel method, chemical vapor deposition (CVD) and physical vapor deposition (PVD). In this paper, an internet of things (IOT) based technology was used to develop the thin film which were coated with the help of dip coating machine. The hardware components DHT11 (Temperature Sensor), ultrasonic sensor and L293Dare linked to Node MCU analog and digital IO pins.
