Tri-axis Magnetic Sensors

There is increasing demand for a sensing function to monitor an object’s status in remote locations as IoT products are expected to grow in the market.

AKM has developed the AK09970N, a tri-axis magnetic sensor that is able to detect magnetic signals in X, Y, and, Z directions. The AK09970N supports wide measurement range with high resolution in tri-axis detection and captures magnetic fields in 3-dimensions.

With these abilities, it is great device for controlling the direction of security cameras and connected home, (smart home, smart house), smart locks, along with door and window open/close detection.
