  3. 17. An implementation of an autonomous IoT system for real-time water quality monitoring with 4G and satellite connection : CatFish - Embedded systems

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi

    Author : Johan Elfing; Daniel Persson; [2022]
    Keywords : CatFish; Embedded System;

    Abstract : This thesis is about implementing an Internet of Things system for measuring water quality in rivers and other aquatic environments with an autonomous water drone, where the data from various components are collected and sent wirelessly to the database in real-time. A Raspberry Pi is connected to the internet through a 4G modem and a wireless satellite communication connection called RockBlock for emergency calls and notifications. READ MORE
