Abstract
Technologically advanced animal production requires more controlled environments, aiming to maximize animal performance and, consequently, the profitability of the activity. To do that, it is necessary to instrument, evaluate and diagnose the various rearing environments. Hence, Precision Animal Production is inserted in this context and aims to effectively meet the general needs of the animal, so that it reach its full productive potential, correcting the divergences between the environment and its well-being to guarantee its comfort. Since Brazil is a country with tropical climate, which is a major obstacle, the proposal of this project is to develop a prototype for embedded system of thermal comfort analysis at low cost. Using sensors and the microcontroller Arduino to manage data, this work fulfilled its objective, with a prototype device (WGV-1c) capable of measuring dry bulb temperature, wet bulb temperature, black globe temperature, relative humidity, BGHI and THI with production cost below that proposed by the market.

Choosing controllers with the possibility of managing mechanisms to control the microenvironment has a good impact on optimizing the production cost and gain of productivity, so it was decided to use the Arduino Mega At2560, which was from the same working platform of the microcontrollers used by Neto et al (2015), Santos (2013), Oliveira (2016) and Oliveira et al (2015)
Summary
The challenge of the contemporary production of agricultural products is intrinsically linked to optimizing processes and production costs. Keeping animals away from their thermoneutrality zone compromise their production due to a nutritional rearrangement, since, in situations of discomfort, they prioritize the energy expenditure for euthermia (Mayorga, 2019). Excessive heat causes a reduction in food intake, which leads to a negative energy balance, but instead of mobilizing fat reserves, the animal uses primary glucose and muscle proteins as fuel. The orthodox methods of measuring and monitoring climatic conditions in animal production still require the recording and activation of thermal control systems manually. The improvement of the automation and information technology industry makes the control of animal sheds more versatile and precise by reducing human intervention.
