nemi WAMS Node
nemi WAMS Node is the wireless sensor node for data acquisition in i4M's Wide Area Monitoring System. In addition to the integrated humidity and temperature sensors, it offers connection options to measure and monitor strain, temperatures or distances (e.g. cracks). nemi WAMS was developed for applications that do not require high data rates but large area coverage with sensors and long battery runtimes. This is made possible by own highly efficient radio technology nemi Link 868. The elimination of cabling enables easy installation even on large assets and structures. Examples for use cases are climate or crack monitoring on bridges or continuous temperature monitoring on rolling bearings in big production facilities.
