Control Systems and Sensors in Agriculture

This video tutorial covers monitoring and control systems, explaining their functions, key terminology, and examples. Monitoring systems use sensors to observe environments, while control systems use actuators to maintain or change conditions. The video discusses various sensor types, their applications, and the differences between analog and digital sensors. It also explores data output methods and provides examples of control systems in agriculture, medical, industrial, and domestic settings. The tutorial concludes with a brief overview of feedback loops and closed-loop systems.
