Where the measurements will be displayed ?

2 choices to create your wireless sensor network:

  • Local single-site solution: you have a small installation (some dataloggers, located near the supervisory position). In this case, the RF Monitor software is appropriate. You install this software on a computer and connect the RF-to-USB Key (radio receiver, provided by Newsteo) to a USB port.

    > More about single-site solution


  • Multi-site solution with remote monitoring: you want to display the measurements of your dataloggers via different PCs located in different sites. The Newsteo Cloud offer allows you to send all the measurements of your recorders to the cloud and access it through a Web application, Webmonitor.
