Magnetometers, such as the LSM9DS1 stick, function by measuring the strength and direction of magnetic fields. They typically operate using principles like the Hall effect or magnetoresistance, which allow them to detect changes in magnetic fields. The discussion highlights the need for more detailed explanations beyond basic concepts, emphasizing the importance of understanding the underlying technology for applications in rocketry and drone development. Resources like Wikipedia and Engineers Garage provide foundational knowledge and different types of magnetometers. A deeper understanding of these principles is crucial for effectively utilizing magnetometers in sensor applications.

Hey everyone!

I'm participating in a sort of beginning class for building rockets and drones. As part of this, I'm to research information about a component of our sensors, specifically, a magnetometer. We're using the LSM9DS1 stick. I'm having a hard time finding any information about how magnetometers work beyond "Magnets and Earth man!" and I was wondering if anyone had deeper insight?

Thanks in advance!

Thread 'UV filter for home central heating?'

Had my central air system checked when it sortta wasn't working. I guess I hadn't replaced the filter. Guy suggested I might want to get a UV filter accessory. He said it would "kill bugs and particulates". I know UV can kill the former, not sure how he thinks it's gonna murder the latter. Now I'm finding out there's more than one type of UV filter: one for the air flow and one for the coil. He was suggesting we might get one for the air flow, but now we'll have to change the bulb...
