This thesis will look into theoretical aspect, implementation and design of data collection and data communication systems. The core system that this thesis use as a data collection system is a thermal water system that exploit heat exchange from a well. Most problems that occur in heat transfer systems can be avoided by implement a automatic surveillance system. This thesis will review basic functionality of the intended thermal system and operative problems and further propose a surveillance system using theory in data collection and data transmission- To transfer the data collected from the thermal system a communication protocol called Message Queuing Telemetry Transport (MQTT) is used. MQTT is an OASIS standard messaging protocol and is designed as an lightweight publish/subscribe messaging transport. MQTT is used in a wide variety of use cases within different sectors to automate control systems. Further this thesis will also provide insights in a relatively new LPWAN protocol called 802.11ah (Wi-Fi HaLow) and how it will deal with the requirements for the Internet of Things (IoT) and smart environments. This include looking into functionality and existing research, implementation, and testing of the protocol to analyze performance.
