ABSTRACT

This paper introduces a systematic approach to design and realize a temp and volume based liquid mixing system using three low cost micro controllers. The primary function of this system is to mix different liquids of required ratio and temperature. The architecture of mixing system consists of two sub systems. They are 1) Electronic sub system 2) Mechanical sub system. In this paper the electronic sub system is developed with the help of three Atmel AT89S51micro controllers for controlling and hand shaking purposes, Two LM35 sensors for sensing temperature and ADC’S are used. The mechanical sub system consists of two geared DC motors to allow the liquids in required ratio for mixing.
