Energy saving and Congestion avoidance are the crucial issues in wireless sensor networks. In existing paper consider mostly how to reduce energy without data information, importance and timing issue. In this paper to overcome this issue by effective utilization of adaptive duty cycle terminology in Energy Efficient Data Transmission Control (EEDTC) algorithm in a real time application. The data transmission is control by using different duty cycle task (RTOS task-Real Time Operating System Task) for different data types. Duty cycle control for Real time application is a crucial issue because of timing problem. This is adaptively achieved using priority based data transmission in wireless sensor networks.

Managing water consumption is important for life preservation. Knowing water consumption at homes can have a great impact on water saving. There is a global water crisis due to increasing population growth, climate change, increasing consumption. Giving a report about the state of the planet’s water, especially in developing countries, the report describes the outlook for future generations as worries. To visually check water taps in the house consumes time and requires a family member to be at the house. To remotely do so, we propose a system that monitors, alerts the user and allows the user to control the water flow through taps whenever there is an unusual reading of the water usage at home. The Water Flow Monitoring and Controlling System is an android- based mobile application. It is equipped with external hardware to sense a tap’s water flow rate and control which means turning on or off the water supply line whenever necessary. Registered users can login and view their house’s current water flowage from the mobile application. The external hardware updates the water flow rate at every specified time to a database through the Internet connection. If the users decide to turn on or off the water supply taps at their homes, it can be done through the on or off button provided in the mobile application. A user’s on or off instruction is set within the database. The hardware receives this instruction and performs the desired action.
