Description
The 7Semi MMC5983MA Micro Magnetometer is a compact 3-axis magnetic field sensor breakout module based on the MMC5983MA magnetic sensor. It measures magnetic field strength along three orthogonal axes and provides digital output over a standard interface, making it suitable for compass, navigation, orientation, and magnetic-field measurement applications. The small form factor and low-power design make it ideal for portable devices, drones, robotics, IoT sensors, and electronic compasses.
