AMR Magnetometer
MEMSIC magnetometer is new generation of MEMS sensor based on AMR technology. Compared to the traditional magnetometer based on Hall technology, AMR magnetometer has high accuracy, low noise, low temperature drift. In addition, MEMIC first introduced high performance AMR magnetometer into the consumer market.
Technical Advantages
Higher accuracy up to 1 degree
The offset of AMR magnetometer is not changed along the temperature change
Stable when the magnetic environment is changed
It can use SET or RESET coil for de-gauss. Since the hysteresis is low, it does not need to calibrate the magnetometer frequently when it is disturbed by a strong magnet
Lower noise
AMR sensor has high signal-to-noise ratio, high sensitivity, and low noise
