The Met One 092 barometric pressure sensor brings in modern digital computer technology. An on-board CPU scales pressure measurements, provides temperature compensation and controls communications output.

eTracker

eTracker is a simple, power-efficient station controller with cellular (GSM/CDMA) telemetry which connects sensors directly to the cloud. A data logger is not required. Eliminating more expensive, complex, higher-power consuming data loggers and remote communication devices, stations for all types of monitoring applications can simply use eTracker and gain the ability to access collected data at any Internet based location.
