Tri-axis Magnetic Sensors

There is an increasing demand for sensing functions to monitor an object’s position.  AKM has developed a tri-axis magnetic sensor that is able to detect magnetic signals in X, Y, and Z allowing for a magnetic vector to be analyzed in real time. Low power, 16-bit accuracy and wide measurement range makes this technology ideal for AR/VR gaming, security camera positioning, True Wireless Stereo (TWS), smart home, smart locks, and door/window open/close detection.
This technology can also be utilized for angle detection of rolling or folding screens, position detection of popup cameras in smart phones, tablets, and TV's.
