Low-cost sensor using a dsPIC for measuring a specific heat capacity of liquids

Abstract

This paper describes a low-cost sensor using a microcontroller dsPIC30F6014A. A simple method to measure the specific heat capacity of liquids using transient technique. A sensor has been designed to measure time and temperature accurately which in turn lead to the measurement of the specific heat capacity of liquids. To test the proposed solution in the present work, different liquids have been used include organic compounds, inorganic compounds and polymers. The results obtained using our sensor have been validated using data available in the literature.
