A cloud-hosted database management software that can process and manage all the data collected at project site. The database management system can do analysis and visualization of the sensor data collected from project site/installation locations. The data should be 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.
