1. An on body unit configured to be worn on a user's skin, the on body unit comprising:
(1) sensor electronics, comprising:
a first wireless communication circuitry;
a second wireless communication circuitry, wherein the first wireless communication circuitry and the second wireless communication circuitry are each configured to operate autonomously; and
one or more processors coupled with the first wireless communication circuitry, the second wireless communication circuitry, and a memory; and
(2) a transcutaneous glucose sensor, comprising:
a proximal portion electrically coupled with the sensor electronics; and
a distal portion configured to be positioned under the user's skin and in fluid contact with interstitial fluid,
wherein the memory of the sensor electronics stores instructions that, when executed by the one or more processors, cause the one or more processors to:
receive, by the first wireless communication circuitry, an interrogation signal from a reader device,
transition at least a portion of the sensor electronics, including the second wireless communication circuitry, from an inactive power state to an active power state in response to the interrogation signal,
process time spaced signals received from the transcutaneous glucose sensor to determine if an adverse operating condition is present, and
in response to a determination that the adverse operating condition is present, cause the second wireless communication circuitry to transmit a notification signal indicating the adverse operating condition to the reader device,
wherein the sensor electronics further comprises a circuit board having a conductive layer and an antenna disposed on the conductive layer.
