Aimed at the current interior decoration formaldehyde pollution problems, through the analysis of the metal oxide semiconductor gas sensor characteristics and sensing mechanism, this paper combined with the influence of nanotechnology on sensor performance and designed semiconductor-type ZnO formaldehyde gas sensor. Prepared nano-ZnO using the sol-gel, doped H2PtCl6, La2O3 according to a certain proportion,...
For the problem of gas qualitatively identify in the field of gas detection, this paper is based on the multi-sensor and pattern recognition of neural network, the uniform change voltage of the sensor output is simulated by the gradient descent algorithm, the additional momentum algorithm and the LM algorithm of neural network, then compare the three simulation results of the three algorithms, the...
