    ABSTRACT


    Studies of heats of reactions of binary liquid mixtures are given a
    considerable importance in understanding the nature of molecular interactions.
    Such studies mainly help to know the enthalpies of liquid mixtures. The present
    study deals with design of a simple embedded based system for measuring heat
    of mixing of binary liquid mixtures. The system consists of two units, cell
    assembly and data acquisition system. One of the components of the binary
    mixture is taken into the cell, other component is injected in to the cell through
    appropriate mechanical arrangement. The reaction on mixing causes the
    thermal changes which are sensed by the thermal sensor, that can be measured
    up to 10-4oC. The entire unit is interfaced to LPC 2366 ARM based controller (A
    less power consumption device made by philips). The ARM controller sends the
    data to the Personal Computer through the serial port and software is developed
    to calculate enthalpy values. A comparison of the results obtained with the
    literature data showed good agreement. The designed system can be used as an
    alternative for the measuring heats of mixing of binary liquid mixtures. The
    paper deals with the design aspects both hardware and software features of the
    system.
