Abstract—In this paper describes, construction and working of more efficient and compactable spin coating machine with a low power consumption comparing to that of current spin coating machine available in the market. The spin coating machine consists of stepper motor, syringe system, Dc brushless motor and Arm processor. The machine will coat thin film in a micro level thickness and its spinning speed and flow rate of the liquid has been controlled by the arm processor (LPC 11U24). Thickness of the film is determined by the flow rate and coating time of the spinning machine. Films with good uniformity for various thicknesses have been successfully prepared by using above spin coating machine, a capacitor sensor has been fabricated the above spin coating techniques and studied their physical properties
