R-Log – Radio Data logger

The data logger for wireless networks


R-Log data logger is a line of compact data loggers for environmental monitoring, suitable for portable indoor applications, but also fixed for continuous monitoring. R-Log can be connected to a wide range of LSI Lastem’s sensor. R-Log can receive measurements via radio from radio sensors, or from other R-Log units in order to create a wireless sensor network. Small and flexible, but also powerful and reliable, R-log is used in multi-measurement (different parameters) and multi-point (different measurement points) applications.



  • N. 4/8/16 analog inputs, N 1/4 digital input;
  • 2.4 GHz Zig-Bee radio to receive measurements from radio sensors and other R-Log modules;
  • Auto-recognition of connected sensors;
  • Extremely low power consumption and integrated batteries;
  • N. 50/99 measurements between channels for sensor acquisition and derived quantities;
  • Internal library for calculating derived quantities and mathematical calculations;
  • 8 MB Flash memory;
  • Digital outputs to implement external devices with programmable logics or events;
  • Sensors acquisition rate from 1 s to 12 h;
  • Statistic elaboration rate from 1 s to 12 h;
  • Connection to the PC via RS232 (USB/Ethernet with external accessories);
  • Display and keyboard.


R-Log is used in indoor applications where medium-long term monitoring is required using an easily transportable and installable system. Typically each R-Log module is mounted on a tripod together with a series of sensors. Applications where R-Log is typically used are HVAC tests of buildings, where the user wants to run a campaign to measure thermal quantities on various points simultaneously with a duration from a few hours to several days.
