IoT monitoring and control prototype with Zabbix and LoRa communication, for Tilapia Biofloc systems

In this work, a monitoring prototype is made for the treatment of tilapia farming through sensors and the use of actuators to control the physicochemical parameters of the water, using the Zabbix platform for the visualization of the key variables, in addition to the use of the LoRa communication protocol, all under the Internet of Things environment, to have a set of nodes and carry out better control in a biofloc farming farm. A study is carried out on the LoRa technology applicable to IoT environments in different devices and development boards. The technologies are chosen, and the user interface design is configured on an opensource platform called Zabbix that allows the visualization of the data received by the IoT prototype. Finally, the Hardware is developed with an ESP32 development board with LoRa included from the Heltec brand and temperature sensors (DS18B0), PH (PH-4502C), DTS (Analog TDS Meter) and oxygen along with the software that is responsible for the data emission with Zabbix. During the tests of the work it is concluded that the prototype with sensors meets the objectives proposed in this work.
