This paper is proposed to improve the efficiency of the air pump for Air Mattress system. The Air Mattress System comprises of Compressor, Stepper Motor, Speed controller. The air from the atmosphere is filtered through filter and then injected to compressor where obtained high pressure air is pumped into air passage valve. The air passage and control dial valve is designed as per inflation and deflation of air in air mattress. Alternating pressure is obtained by system by replacing the plastic gear by speed control drive. The speed of the stepper motor is controlled by PIC microcontroller. The System is tested and simulated with the help of PROTEUS/MP Lab.Alternating pressure is obtained by changing the direction of control dial valve at slow rate. This slow rate is achieved by controlling the speed of the motor at 1/10 rev per min. To avoid the friction, spring load is used between motor block and control dial valve. The proposed method improves durability of the whole.

Keywords : PIC microcontroller, Stepper Motor, Control Dial Valve, Vibrating Armature Compressor , Air Mattress.
