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 CMPS12 - Tilt Compensated Compass Module

Code: SEN-010087

The CMPS12 is our 4th generation tilt compensated compass. Employing a 3-axis magnetometer, a 3-axis gyro and a 3-axis accelerometer. At the core of the module is the superb BNO055 running algorithms to remove the errors caused by tilting of the PCB. Powered from 3.6-5V @18mA the compass outputs ...

Hall-Effect Sensor - AH1815 (Non-Latching)

Code: SKU-004677

The AH1815 is an integrated Hall-Effect non-latched sensor. That’s nice but what does it do? Holding a magnet near the sensor will cause the output pin to toggle. This makes for a robust presence sensor. A reed sensor also works nicely, but can be limited by the glass encapsulation and size.
