Gateway

Model EWG-01 Overview

Model EWG-01 gateway is an important device of the wireless network system. It acts as a network node for wireless communication with different types of nodes (vibrating wire, analog, digital and relay nodes) having altogether different transmission protocols. The gateway serves as an exit point/central hub for wireless data obtained from the sensors as the readings pass through or communicate with the gateway prior to being routed to a FTP or cloud server.In addition it passes control messages through the network to ensure seamless operation.

The gateway can collect data from practically any type of sensor like vibrating wire, analog and digital through suitable nodes. Options of single channel and multi-channel nodes are available to give user flexibility to make better cost effective selection, depending on site requirements.A cloud-hosted data management and configuration software is used to manage the network. The configuration is done with an easy to use smartphone application that comes free with the system. Gateway uploads the collected sensor data to the central/cloud server.

Drishti, a cloud-hosted data management software is available to process and manage the huge data collected at project site. The data is accessible 24 x 7, in meaningful visual formats, to all the related authorities. The system can generate automatic reports and provide automated alerts over SMS or email for any reading crossing the pre-defined alert levels.
