1. A method of applying an on skin sensor assembly to a skin of a host, wherein the on-skin sensor assembly comprises a housing secured to an applicator, wherein the housing is configured to receive an electronics unit, the method comprising:
- positioning an applicator proximate a skin of a host, the applicator comprising a sensor insertion assembly, a trigger, and a base;
inserting an electronics unit into the housing, wherein the electronics unit is configured to generate analyte information based on a signal from a sensor;
activating the trigger, thereby causing the sensor insertion assembly to insert the sensor into the host, to cause the electronics unit to secure to the housing such that the sensor electrically contacts the electronics unit, and to cause the housing to detach from the base; and
removing the applicator away from the skin of the host, whereby the on-skin sensor assembly comprising the housing, the electronics unit, and the inserted sensor remains on the skin of the host.

Abstract
The present embodiments relate generally to systems and methods for measuring an analyte in a host. More particularly, the present embodiments provide sensor applicators and methods of use with pushbutton activation that implant the sensor, withdraw the insertion needle, engage the transmitter with the housing, and disengage the applicator from the housing, all in one smooth motion. Some embodiments contemplate engagement of the transmitter with the housing after release of the applicator.
