2 WR LOG WIRELESS MONITORING SYSTEM WR LOG wireless monitoring system is composed by a number of nodes to which instruments are connected, and a gateway communicating with nodes through long range radio. Nodes are configured through an Android APP while the gateway have a web server on-board for the set-up. WR LOG is a low power consumption system that can reach up to 10 years battery life. Distance between node and gateway can arrive up to 15 km. The gateway can push data on a FTP server; remote connection to gateway is allowed for data download and set-up. FEATURES Long-range communication of over 15km Truly low-power, 10 years of unattended runtime Wireless LPWA communication Supports most structural and geotechnical instruments User-friendly web software BENEFITS Remotely monitor hard-to-access infrastructures Cover a wide area with geotechnical sensors Easily add sensors to extend measurement range Save resources through fast implementation Diminish risks and make operations safer Meet the essential requirements of the EMC Directive 2014/30/EU and RED directive 2014/53/EU WR LOG WIRELESS MONITORING SYSTEM 2
