Abstract
A magnetic sensor may detect a system-level error, associated with a sensor system that includes the magnetic sensor, based on one or more physical parameters as determined at the magnetic sensor. The magnetic sensor may provide an indication of the system-level error in an output signal. The one or more physical parameters may include a temperature at the magnetic sensor, a temperature drift of the magnetic sensor, a supply voltage at the magnetic sensor, an amount of humidity at the magnetic sensor, or an amount of pressure at the magnetic sensor.
