R-GWR

ModBUS Gateway / Radio Hub LoRa for wireless sensors

R-GWR is a system of interface and measuring industrial, civil, or environmental parameters. The device creates a network of remote sensors connected with LoRa radio technology (863-865 MHz) and accessible via ModBUS RTU/TCP-IP protocol. R-GWR is ModBUS TCP-IP server and ModBUS RTU slave. The unit operates as a radio hub capable of managing up to 32 sensors, each capable of acquiring 1) an integrated temperature/humidity signal, 2) a generic digital/analog input (0-30 Vdc) from a terminal or a counter @16bit with maximum frequency 1Hz. The sensors' power supply is provided by lithium batteries whose duration can vary up to a maximum of 36 months depending on the configuration of use. Data transmission from the sensor to the device occurs 1) at the programmed time, 2) on an event, and 3) via an integrated pairing button. R-GWR supports Ethernet and the ModBUS TCP-IP protocol for connection with remote management systems and up to 8 TCP-IP client nodes.
