Sensor fusion is a way of combining information from sensors (like a microphone, camera, or radar) to get a better understanding of what is happening around us. When these sensors come together, they can provide us with more accurate data than any of them could individually. For example, a microphone can detect sound waves, but a camera can see what the sound waves look like. When these two work together, we get a much clearer picture of what is happening in our environment.
