In some embodiments, the continuous analyte sensor system comprises a sensor electronics module that includes power saving features. One feature includes a low power measurement circuit that can be switched between a measurement mode and a low power mode, in which charging circuitry continues to apply power to electrodes of a sensor during the low power mode. In addition, the sensor electronics module can be switched between in a low power storage mode higher power operational mode via a switch. The switch can include a reed switch or optical switch, for example. A validation routine can also be implemented to ensure an interrupt signal sent from the switch is valid. The continuous analyte sensor can be physically connected to a sensor electronics module, which is in direct wireless communication with a plurality of different display devices. ## Claims ### Claim at position 1 1-20. (canceled) ### Claim 21 A system for continuous measurement of an analyte in a host, the system comprising: a continuous analyte sensor; and a sensor electronics module coupled to the continuous analyte sensor, the sensor electronics module comprising a switch configured to switch the sensor electronics module between a first low power mode and a second higher power mode, wherein the switch is configured to switch from the first low power mode to the second higher power mode when the sensor electronics module detects a signal output of the sensor above a predetermined threshold, wherein the detecting comprises the sensor electronics module performing a sensor measurement in the first low power mode. ### Claim 22 (depends on 21) The system of claim 21, wherein power consumption due to wireless transmission and/or receipt of data has been turned off in the first low power mode. ### Claim 23 (depends on 21) The system of claim 21, wherein the system further comprises a mounting unit (240) configured to hold a portion of the continuous analyte sensor, wherein the electronics module is configured to couple to the mounting unit. ### Claim 24 (depends on 21) The system of claim 21, wherein the sensor electronics module is configured to periodically perform sensor measurements in the first low power mode. ### Claim 25 (depends on 21) The system of claim 21, wherein a telemetry module of the sensor electronics module has been turned off during the first low power mode. ### Claim 26 (depends on 25) The system of claim 25, wherein the telemetry module is for transmitting data between the sensor electronics module and one or more display devices. ### Claim 27 (depends on 26) The system of claim 26 comprising the one or more display devices. ### Claim 28 (depends on 21) The system of claim 21 configured so that if the sensor electronics module measures a sensor reading below the predetermined threshold, then the sensor electronics module remains in the low power mode. ### Claim 29 (depends on 21) The system of claim 21, wherein the threshold is based on values that would indicate the sensor electronics module is not operatively connected to the sensor or, even if connected to the sensor, the sensor is not implanted in a host. ### Claim 30 A method of increasing a useful life of a sensor electronics module coupled to a continuous analyte sensor, the method comprising: entering the sensor electronics module into a low power mode when not in use, thereby extending the useful life of the sensor electronics module; performing a sensor measurement in the low power mode; and causing the sensor electronics module to enter a higher power consuming, operational mode when a sensor reading of the continuous analyte sensor above a predetermined threshold is detected. ### Claim 31 (depends on 30) The method of claim 30, comprising turning off power consumption by the sensor electronics module due to wireless transmission and/or receipt of data in the low power mode. ### Claim 32 (depends on 30) The method of claim 30, comprising periodically performing a sensor measurement in the low power mode. ### Claim 33 (depends on 30) The method of claim 30, comprising turning off a telemetry module in the low power mode. ### Claim 34 (depends on 30) The method of claim 30, wherein if the sensor electronics module measures a sensor reading of the continuous analyte sensor below a predetermined threshold, then the sensor electronics module remains in the low power mode. ### Claim 35 (depends on 34) The method of claim 34, wherein the threshold is selected based on values that would indicate the sensor electronics module is not operatively connected to the sensor or, even if connected to the sensor, the sensor is not implanted in a host.
