Logotronic - Compact IoT Data Storage and Data Transmission Module

Compact data storage and data transmission module for a wide range of measurement tasks

• RS485 fieldbus interface for connection of sensors or Gealog measuring interfaces
• Display and keypad for operation without control unit
• Bluetooth short-range radio for operation with control unit
• Integrated IoT modem
• Easy configuration using the GealogApp application
• Data transfer to an FTP server at programmable time intervals. Local measured value memory for buffering the measured data.
• Visualization of measurement data in the web browser using the GealogNet database.
• Data transfer unencrypted (FTP) or encrypted using FTPS.
• Use of the latest mobile technologies LTE CAT-M1 or LTE N1 (NB-IoT)
• Long battery life through the use of sophisticated energy-saving methods.
• Housing for DIN-rail mounting

Simple design, high operational reliability

The sensor configuration is programmed in the firmware of the Gealog Compact IoT. In addition, further parameters such as measurement rate and data transfer rate are dynamically configured with the help of the GealogApp. The Gealog Compact IoT retrieves the measured values from the sensors, stores them in the measured value memory and periodically transmits the collected measured values to an ftp server via FTP or FTPS protocol (encrypted). The modern mobile radio standards Cat-M1 or NB-IoT are used for this purpose, which are optimally suited for applications in environmental measurement technology due to their specifications.

Data transmission via mobile radio, visualization in the browser

In addition to time savings due to reduced measuring station visit intervals, data transmission also offers the advantage of ongoing automated control of the measuring station. Logotronic offers the GealogNet system as an option to the Gealog micro SG, where the incoming data is immediately accessible on the web via browser. Various options for monitoring incoming data create a high level of data security. The GealogNet database can be hosted by Logotronic, but can also be installed on their server.

State-of-the-art mobile communications

The Gealog Kompakt IoT uses the latest mobile radio standards for data transmission for this application, either LTE CAT-M1 or LTE N1 (NB-IoT). By using low radio frequencies, the penetration of obstacles (e.g. concrete walls) is much better than with standard LTE. The Gealog Compact IoT still transmits where normal cellular modems have to give up.
