||A scientific sensor logging system that can be deployed on a diverse range of environmental long-term monitoring platforms. Scientific sensors are integrated into the system. In addition to sensor data, sensor configuration are logged and the system allows two-way communication. The logger connects to a PC based system via telemetry, which displays and archive real time data, provide system configuration and enables sensors to be controlled remotely. Supports analog, digital, RS-232, RS-422, RS-485, CANBUS, SDI-12, and PUCK sensor interfaces. Supported telemetry options include VHF, cellular (GPRS/CDMA) and satellite transmission, landline phone, serial interface, and TCP/IP Ethernet.
