e-Compass
  Voltafield Geomagnetic Sensor is developed based on AMR technology. It is high sensitivity, low noise and low power compared to Hall sensor. With its know-how, VTC Geomagnetic Sensor detects azimuth with total precision. In addition, VTC provides the best solution- small and thin package for space-limited products, such as smart phones and wearable devices.

  We also provide software compensation solutions which allow user to get exact location in a non-horizontal environment using e-Compass. Thus, it could be applied to different measurement purpose besides e-Compass, such as traffic flow detector, GPS, Driverless Car and etc.Complete solution and support are provided for customers in their need of various applications.

  In the future, we will continue developing the advance software and Geomagnetic Sensor with our innovative technology in order to provide the best solutions for our customers.
