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 AK09970, a tri-axis magnetic sensor that is able to detect magnetic signals in X, Y, and, Z directions. The AK09970 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.
