Later many improved and reliable versions were developed. Digital Compass Sensor that is used in the smartphone is based on the magnetometer sensor. The resistance of the magnetic sensor present in magnetometer changes in proportional to the magnetic field present in a particular direction.
The magnetometer measures the magnetic field strength and orientation. This information from magnetometer is stored by the CPU as digital data. This Sensor always points towards the Geometric North. The Compass found in electric devices is a solid-state sensor. Usually, two or three magnetic sensors are present on the device from which the microprocessor can read data and detects the orientation of the device.
There are two configurations of Compass Sensors available based on there working principle. They are the Magnetic Compass and Gyro Compass. Magnetic Compass contains a magnetic element to detect the magnetic field. Don't miss out. Send a tip.
