The blueberry D2 is a versatile, reliable and rugged data logger for serial sensor networks and SCADA integration.

A broad range of interfaces and communication protocols allows for the integration of a broad range of digital sensors and actuators.
With 3 independent serial interfaces (2x RS-485, 1x RS-232) supporting baud rates from 1,200 up to 115,200, high temporal resolutions can be achieved even with many devices connected. Up to 512 MB of data are buffered on the logger and accessible either wirelessly via GSM, or wired using Ethernet or optical fiber. The logger can determine its position and the exact time using the integrated GPS receiver. A user-friendly web interface makes remote configuration and data inspection simple and easy.
