The book delves into the design and construction of a solar tracking system prototype with single-axis freedom, emphasizing the efficiency of solar energy production. It explains how the system utilizes a NodeMcu microcontroller and LDR sensors to orient the solar panel for optimal sun exposure. By adjusting the panel's position based on sunlight detection, the system maximizes energy capture. The discussion highlights the advantages of using a DC motor for its simplicity, high torque, and appropriate speed for this application, despite the initial installation costs.

The book explores the generation and transmission of bulk electrical power through various methods, including hydro, thermal, and geothermal sources, as well as off-grid diesel generators and wind power. It discusses the technical aspects of voltage levels, emphasizing the importance of high voltage transmission to minimize energy losses. The relationship between load centers and generating stations is examined, highlighting how power is distributed based on demand across residential, industrial, and commercial sectors, addressing peak and off-peak load considerations.

A epidemia de COVID-19 acelerou a adoção de tecnologias digitais na saúde, destacando a importância de sensores e IoT para cuidados inteligentes. O monitoramento remoto, a telemedicina e a gestão eficaz de recursos são essenciais. O capítulo aborda dispositivos vestíveis e questões éticas relacionadas à privacidade na saúde digital.

A energia solar se destaca entre as renováveis pela sua rápida popularidade. Este projeto explora a construção de um protótipo de sistema de seguimento solar com um eixo de liberdade, utilizando um microcontrolador NodeMcu. O sensor LDR orienta o motor DC para otimizar a captação de raios solares, maximizando a eficiência.
