Remote monitoring of the ecological qualty of water

V diplomskem delu je prikaz sistema za daljinsko spremljanje ekološke kvalitete voda in zajem merilnih podatkov z mbed krmilnikom in WiFly modulom, ki brezžično posreduje podatke naprej na Android aplikacijo. Prikazan je način, kako je izdelan sistem za zajem merilnih podatkov mbed, komunikacija med merilnim sistemom WTW prek A/D kartice, ki mA spremeni v volte, z mbed modulom in opis tega sistema. Prikazan pa je tudi način, kako izdelati aplikacijo v Android okolju, postopek, kako Android aplikacija in celotni merilni sistem komunicirata med sabo. Opisan je tudi način, kako se preprosto aplikacijo naredi, v prilogi je priložena koda izdelave, kako se jo uporablja, prikaz izmerjenih podatkov na njej v številčni obliki in tudi v obliki grafa. Razložen je tudi način pošiljanja merilnih podatkov na računalnik, kjer se jih lahko naknadno preoblikuje v obliko, primerno za nadaljnjo obdelavo in uporabo. In the diploma thesis can be found presentation of system for remote monitoring of the ecological quality of water, how to capture measurement data with the mbed controller and WiFly module who wirelessly transmit data on Android app. Presented is the way how the systems mbed is build and how it can capture measurement data, the communication between measuring system WTW through the A/D cards, who transmit mAMPER signal in I2C digital signal, the mbed module and a description of all mesuring system. Here is also shown the way how to develop an application in the Android environment, the process of how Android applications and the entire measuring system communicate with each other. It is also described the way how it can simply be make an application, in an annex is attached programming code of app, how it can be used, how it the display data of measurings in numerical form, as well as in the form of a graph. Here is also explained the way how to send measuring data to the computer, where it they can be subsequently converted into a form suitable for further processing and use.
