SDI-12 data communications

  • asynchronous serial communications protocol for intelligent micro-processor based sensors
  • sensor typically takes a measurement, makes computations based on the raw sensor reading, and outputs the measured data in engineering units
  • allows connection of set of sensors serially on one cable line

Mini32 software

Mini 32 P C app
  • graphically oriented software intended for work with long time series
  • fast calculation of hourly, daily, montly values
  • fast brief statistics
  • built-in efficient commands for summation and min-max-average calculation
