True cloud-based sensor configuration, logging, reporting and data analysis all-in-one.

eTracker is the gateway between the sensors and the cloud. Data communication and IT infrastructure are merged under one user interface experience. eTracker was designed from the ground up to embrace the current and future trends of cloud-based remote data acquisition and the "Internet of Things" (IoT) revolution. This paradigm shift centralizes all the historically isolated processes of remote configuration, programming, logging, and telemetry. Configuration, logging, data processing and analysis is now done in the cloud, eliminating time and cost in programming and maintaining expensive, complex data loggers and communication devices at each remote location.

 

  • Cellular-based telemetry (GSM or CDMA) and station controller.
  • Direct Internet compliant data stream using HTTP/HTTPS.
  • Sensor measurements stored on easily-accessible SD card.
  • Cloud logging: all sensor data is forwarded to the cloud for processing, logging, retrieval and resulting action.
  • Integrated sensor interface with ports: 4 analog, 4 pulse, SDI-12 (up to 62 SDI-12 sensors).
  • Approximately 20X typical improvement in power consumption vs. typical cellular telemetry.
  • Intelligent data management, data buffering, and network verification to ensure successful transmission of critical data.
