The recommended operating temperature range for the MPR084EJR2 is -40°C to 125°C, although it can tolerate storage temperatures from -55°C to 150°C.
Calibration involves applying a known magnetic field to the sensor and adjusting the offset and sensitivity values to achieve accurate readings. A detailed calibration procedure can be found in the application note AN4246.
The MPR084EJR2 can measure magnetic fields up to ±8 Gauss (800 μT) in the x- and y-axes, and ±12 Gauss (1200 μT) in the z-axis.
The MPR084EJR2 communicates via a standard I²C (Inter-Integrated Circuit) interface, which can be connected to a microcontroller's I²C bus. The sensor's address is 0x1C or 0x1E, depending on the state of the ADD pin.
The typical power consumption of the MPR084EJR2 is 1.5 mA at 2.5 V, with a maximum current consumption of 2.5 mA.
