What sensors do I need to detect magnetic "take off"? I want to build a sensor using arduino (or any other esp) measuring the release of a leg on a floor panel. I've build a prototype using copper plates and a BBC Micro:bit, which works fairly well. But I want to use magnetic sensors, determining release of the leg.
My education on magnetic is - simple. I know it exists. I know it's one of four basic forces in nature (ha!). But I don't know how to measure it using electronic circuits (I'm new to this topic).
Imagine one person stands on a plate, wearing magnets on his foot (say &quot;magnetic socks&quot;). I want to immediately detect when the person raises his leg. What kind of sensors do I need?
You have two options here, either a Hall Effect sensor or an Inductive Sensor. The hall effect sensor is probably the best option. This will likely need some calibration on your end to identify the exact value you record at &quot;Take Off&quot; for your setup.
