This work focuses basically on the design and analysis of simple and low cost hardware systems efficiency for temperature measurement in agricultural area. The main objective is to prove quantitatively, through statistical data analysis, to what extent a simple hardware designed with inexpensive components can be used safely in the indoor temperature measurement in farm buildings, such as greenhouses, warehouse or silos. To verify the of simple hardware efficiency, its data were compared with data from measurements with a high performance LabVIEW platform. This work proved that a simple hardware based on a microcontroller and the LM35 sensor can perform well. It presented a good accuracy but a relatively low precision that can be improved when performed some consecutive signal sampling and then used its average value. Although there are many papers that explain these components, this work has the distinction of presenting a data analysis in numerical form and using high performance systems to ensure critical data comparison.

The civil construction sector has been stimulated to industrialize itself by the adoption of Lean Construction practices in its constructive process. Given this fact, this research verify and identify Lean Tools and the level of application of these Tools in construction companies in the State of São Paulo, in order to be able to notice which Lean Concepts generate the highest benefits to these companies. The research method used was a survey applied only between construction companies that have some type of quality certificate. From the results, a data analysis was made in order to note the constructor's situation in relation to Lean Construction and, based on this analysis, verify the impact of the Lean Principles on the competitiveness of these companies and on the business performance. This way, it was possible to note a high level of application the Lean Tools by the responding companies. It also became clear, by means of this work: the strong influence of the concepts of Flow, of Continuous Improvement and of methods of prevention and resolutions of problems on the overall companies performance
