Objective
The aim of this course is to enable the student to understand and develop instrumentation and
automation systems applied to agricultural systems. For this, basic concepts of electrical and
electronics are presented and discussed. These will serve as support to understand the classical
components and processes as measure instruments and data acquisition, sensors, actuators and data
processing as, their respective software and how it apply in agro-industrial systems. In addition,
through practices with sensors and data acquisition hardware, the aim is to strengthen the concepts
discussed and enable the student to handle modern hardware and software tools for automation and
instrumentation.
