Diseño de un sistema basado en IOT para monitorear la nutrición del suelo en cultivos de cacao

Abstract

The project was carried out on the investigation of soil nutrition necessary for the cultivation of cocoa in Ecuador. The parameters to be measured were the nutrients: nitrogen, phosphorus and potassium, the data are processed and sent by a connectivity protocol of Wi-Fi technology. A serial NPK sensor was used to read the nutrient data using an RS485 interface and a UART so that the data can be processed in a microcontroller. For data visualization, an OLED display is used, in conjunction with serial communication using Pycom FiPy 1.0, to display the data on an Internet platform called Pybytes. In addition, an SD memory card is used to keep track of nutrient levels.
