1. A system for controlling activation of analyte sensor electronics circuitry, the system comprising:
an applicator comprising at least an applicator body, wherein a magnet is disposed in the applicator body proximate a magnetic sensor;
an analyte sensor;
the magnetic sensor configured to trigger a signal responsive to detecting a change in proximity of the magnet caused by the magnet being moved a predetermined distance relative to the magnetic sensor, and detecting a change in a spatial orientation of the magnetic sensor relative to the magnet, wherein the change in the spatial orientation changes an alignment of a magnetic field of the magnet with respect to the magnetic sensor; and
the analyte sensor electronics circuitry configured to:
transition into an operational state responsive to the signal indicating that the analyte sensor electronics circuitry has been deployed from the applicator body; and
upon transitioning into the operational state, receive an indication of one or more analyte concentration values from the analyte sensor.
