Model EWN-01A/04A series of wireless analog nodes are designed to expand the data collection possibilities from analog sensors (with millivolt, voltage, 4-20 mA, wheatstone bridge output) via wireless RF network, eliminating the need for running lengthy cables. These are especially useful at locations where sensors are distributed over wide areas and running cable lengths to long distances can be tricky and /or at locations where construction activity can disrupt the running sensor cables.
The analog node is available in single and multi channel variants to connect one analog sensor (model EWN-01A), to up to four sensors (model EWN-04A). The complete range of analog sensors can be connected to wireless node including:
The wireless analog node is a highly reliable integrated system which collects sensor data and transmits measurements through long rage radio frequency wireless communication network to the Gateway. 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.
