Comunicação sem fio entre sensores aplicada a sistemas de irrigação

Abstract

This work presents the study and development of a device that allows wireless communication between sensors and an electronic device developed by student Lucas B. Tsuchiya, which aims to control, monitor and activate irrigation systems. The main functionality of this project is the removal of cables used to communicate between the sensors and the control module, enabling more robust applications, due to: Simplified assembly of all acquisition equipment, increased range between sensors/ controller module and the irrelevance of using specific cables. The project will consist of several sensors for data acquisition, three ESP32 microcontrollers for the development of wireless communication and without internet access and in addition to the microcontrollers for data acquisition, the project will have a Raspberry Pi for the development of the drive. From the data collected with the developed equipment, it was possible to demonstrate that wireless communication between sensors using the ESP-NOW and MQTT protocols is efficient and possible to be used in domestic applications and even for large plantations.
