Compass / Magnetic

Compass and Magnetic Sensors

Earths magnetic field can also be read by sensors to provide a bearing or direction. More advanced compass sensors include some additional circuitry to compensate for any tilting of the compass from the horizontal plain as occurs in vehicles moving on the ground or across the sky.

Devantech CMPS11 - Tilt Compensated Compass Module

Code: SEN-10066

The CMPS11 module is a tilt compensated compass. Employing a 3-axis magnetometer and a 3-axis accelerometer and a powerful 16-bit processor, the CMPS11 has been designed to remove the errors caused by tilting of the PCB. Powered from 3.6-5V @35mA the compass outputs the bearing reading via serial...
