Sensor fusion in Wireless Sensor and Actuator Networks (WSANs) is important, particularly in the context of advancing technology and the growing Internet of Things (IoT) landscape. This course offers a comprehensive guide on how to implement sensor fusion filters for processing various types of sensor data. The course is structured to build understanding progressively, starting from basic concepts to more complex implementations. It combines theoretical explanations with practical examples and code snippets in Python, thus bridging the gap between theory and practical application in sensor data processing and analysis.
