GatorByte - Microcontroller Firmware

Title: GatorByte – An Internet of Things-based Low-Cost, Compact, And Real-time Water Resource Monitoring Buoy Abstract: Water-quality monitoring systems available today are usually expensive and have low-temporal resolution and lack spatial dimension entirely. These systems are typically available as stations or handheld devices. Pinpointing sources of pollution using these systems is difficult. This project involves developing a high-resolution free-flowing monitoring buoy that records spatiotemporal water-quality data. The system is highly customizable, and even users with limited experience in programming or electronics can tailor GatorByte for their needs. The platform includes a datalogger, cloud-based server, and visualization tools. The datalogger uses low-cost sensors, electronic peripherals, a 3D-printed enclosure, and Printed Circuit Boards, bringing the cost per unit under $1000. The datalogger uses an NB-IoT-capable Arduino for real-time reporting and visualizing sensor data. The GatorByte records physiochemical water metrics – pH, temperature, dissolved oxygen, electroconductivity, and the current location of the buoy using a GPS module. The datalogger also includes micro-SD storage, and Bluetooth module for on-field diagnostics. Using GatorByte buoy, collection of variations in water quality data in temporal as well as spatial dimension can be achieved in a cost-effective and reliable manner, enabling quick detection and resolution of pollution events. Description: This repository contains the embedded software for the microcontroller on the GatorByte buoy. The GatorByte library containing sub-libraries for supported peripherals and sensors is also included.
