Smart Sensor Block DiagramSmart Sensors
Smart, precise, and simple

NVE Smart Sensors combine the precision and sensitivity of our industry-leading GMR and TMR sensors with sophisticated digital signal processing to create devices with unparalleled accuracy.

This accuracy coupled with easy-to-use digital interface allow for precision magnetic sensing with a lower part count and faster development cycle than ever before. Devices are available in magnetometer and angle sensor configurations, with different precisions and speeds. Magnetometers can be used for proximity sensing or noncontact current sensing.

Breakout boards and Evaluation kits are available for each sensor.
