Gravity: Digital Magnetic Sensor Introduction
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!
Wide voltage range from 3.3V to 5V
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..
