Abstract
An electronic environmental sensor tag includes microsensor elements using magnetic logic devices adapted to detect target chemical and/or target environmental conditions. The microsensor elements operate only periodically to save power, and also include non-volatile memories and communications circuits to allow interrogation and detection of a target condition. The microsensor element state is detected and then processed to identify a detected value for the target chemical. The detected value can be communicated by an antenna element to a separate reader device.
