Sensor-less temperature and humidity estimation using transmission lines

摘要

This paper proposes a sensor-less temperature and humidity measurement technique. Objective of the proposed work is to design an observer to estimate the temperature and humidity from transmitted signal. Transmitted signal through the cable is analyzed for computing the effect of temperature and humidity. For analysis an observer is designed to estimate the temperature and humidity from the derived output of transmission lines and model of transmission lines. In the proposed work a neural network based non parametric model is designed. Once the model is designed it is subjected to test in both simulation and real life. Results show successful implementation of proposed work.
