what's the best way to detect the magnet? Use anther magnet. But it's not sensitive enough. You have to feel it by youself.Right. This magnetic sensor knows whether there is a magnetic object nearby or not. And it correctly tells you through ditigal output.See below picture for a quick demo!
CMPS03 - Magnetic Compass Introduction
This CMPS03 is Discontinued Now, We recommend other Magnetic Sensors as a suitable replacement.
The Devantech Magnetic Compass Module CMPS03 identifies the angle of rotation in relation to the Earth's magnetic field. 0.1 degree of resolution and 3 to 4 degrees of accuracy. Can easily be connected to microcontrollers such as the BasicX or BasicATOM. Built by Devantech, this..
