Abstract. A dedicated microcontroller-based density measurement system is developed to measure density of solids. A strain gauge and a thermocouple sensor are used to measure the mass and temperature of the sample. A three layer neural network is used to train the data for atomic number, temperature and density of sample using back propagation algorithm. After training the neural network, it is used to compute the density at various temperatures.
