Abstract
In recent years the demand for water has increased manifolds, and this has become a major challenge throughout the world. Cities in Southern Africa and India are nearing Day Zero, where people will not have sufficient water for their day to day needs. One of the major reasons for this crisis is the lack of proper water management on a large scale. To overcome this problem we present an IoT based design for water monitoring and control approach which supports internet based data collection on real time basis. The device comprises of: a central server (Central Hub), the IOT Module, the switching unit and the Zigbee module. IoT is not a single technology; rather it is an agglomeration of various technologies that work together in tandem which uses sensors and testers. These are devices which help in interacting with the physical environment to determine the water level and quality. The centralized hub is responsible for supplying water to different substations. The substations are present at various key locations throughout the city, based on the requirements of that particular area, water is supplied to that substation. The IOT assists the Central Hub, in integration of communications, control, and information processing across the entire network. This aids us in determining the requiredvolume and quality of water, at each units in one particular sector and it also provides the control over the supply of water, to the central hubthrough a remote access,Based on the paucityor excess water level in a tank, the centralized hub monitors and shares the water among the localized tanks or resupplies water from its reservoir. This scenario requires an establishment of a personal area network which can be done efficiently through wireless connections. The quality of water can be improved by subjecting the water to UV treatment before supplying them to individual households. Fluoride content level along with hardness checking is also done using respective test meters.

Abstract
Cruise control and accident avoidance have been a major point of interest in the recent past with the sophistication of vehicles. Driving assistance is provided with cameras and sensors in most of the high-end vehicles and is furnished as an additional system to them. Increasing population and rapid aging have increased the cause of accidents especially, of the senior age group. Smart and automatic driving systems have been developed to provide assistance. The on-board system processes are not utilized to the extent they have been developed and thereby causing misguidance to the users. In this project an embedded system is developed with omnipresent modules that are communicating with each other and the system processing unit designed for the vehicle. It helps the driver to identify the vehicles and monitor their speed. This system will also guide them to know the traffic present in the lane they are traveling and will help them to re-route in case of emergency.
