Wireless Data Logging System

The Wireless Data Logging System allows exact monitoring of several physical values in a large variety of application fields.

A data recording system consists generally of:

  • Wireless data loggers
  • Acquisition system / base unit
  • Software for data evaluation

The base unit serves as an interface between the data loggers, placed in the measurement sites, and the PC or PLC (Programmable Logic Controller).
The collected data are received wirelessly and transmitted to the PC or PLC via:

  • USB
  • Ethernet, RS485
  • GSM / GPRS
  • Wi-Fi

The base unit is powered by:

  • PC USB port
  • Internal rechargeable backup battery
  • External power adapter (optional).

If the PC is not connected, the internal memory can store the measurement data received from the data loggers (Ring type memory: if the memory is full, the oldest data will be overwritten by the new ones).

Further functions:

  • Acoustic alarm
  • Wall mounting (with supplied plastic support) or fixed installation (optional)
  • Expandable up to 245 data loggers

In order to increase the distance between the data loggers and the base unit, a signal repeater can be installed.

Data loggers are available for monitoring of:

  • Temperature
  • Humidity
  • Atmospheric and differential pressure
  • Illuminance (lux)
  • UVA, UVB and UVC irradiance
  • Carbon monoxide (CO)
  • Carbon dioxide (CO2)
  • Solar radiation
  • Precipitation
  • Wind speed and direction
  • Leaf wetness
  • Soil volumetric water content

Applications:

  • Greenhouses and agriculture
  • Warehouses
  • Refrigerated containers and cold storage
  • Transportation of perishable goods
  • Laboratories
  • Environmental analyses (Air quality, meteorology and hydrology)
  • Industrial processes
  • Buildings, offices, schools, etc.
