description

Master's thesis in Information- and communication technology (IKT590) This project proposes a self-powered long-range wireless sensor node based on Long Range Wide Area Network (LoRaWAN) with various sensing capabilities. The nodes have been designed in such a way that these are self-sustainable throughout the components’ lifespan. These are completely powered by ambient solar energy harvesting. Also, these nodes can be deployed on a large scale and are maintenance-free. In addition, these nodes can be deployed in remote places where the accessibility is limited, and maintenance is difficult. The wireless sensor nodes can be deployed both in indoor and outdoor environments with sufficient light levels for the solar panel, such as indoor lights in the indoor environment and ambient sunlight in the outdoor environment. The fully functional wireless sensor node is designed and tested. The developed long-range node has a power consumption that is lower in comparison to the amount of power harvested in the ambient environment. The designed node senses the air quality parameters: the level of carbon dioxide, amount of humidity, pressure levels, temperature, and the total organic volatile compounds and gases. It is possible to add several other sensors without modifying the base hardware.
