Abstract

Systems and methods for processing, transmitting, and displaying data received from a continuous analyte (e.g., glucose) sensor are provided. A sensor system can comprise a sensor electronics module that includes power saving features, e.g., a low power measurement circuit that can be switched between a measurement mode and a low power mode, wherein charging circuitry continues to apply power to electrodes of a sensor during the low power mode. The sensor electronics module can be switched between a low power storage mode and a higher power operational mode via a switch, e.g., a reed switch or optical switch. A validation routine can be implemented to ensure an interrupt signal sent from the switch is valid. The sensor can be physically connected to the sensor electronics module in direct wireless communication with a plurality of different display devices.
