This paper aims at providing a solution to the problems faced in the existing analogue water meters that include the low accuracy in flow measurement, air valve issue, manual billing system and uneven distribution of water. The SMART AQUA METER-SAM overcomes these limitations by introducing a smart electronic measurement system. It automates the billing system using a low power wireless technology-ZigBee[1]. Water consumption is monitored in real time and the data is transmitted to the data centre via ZigBee for storage, billing and maintenance purposes. A human machine interface is designed using NI LabVIEW. An experimental result provides the validity for the proposed work.

Energy plays an important role in the monetary and social expansion of any country. However, there used to be a general deficiency of rural energy development policies that focuses on agriculture. Agriculture has a dual role, i.e. it acts as an energy user in crops as well as an energy supplier in solar electricity generation. Rajasthan, the largest state of India, is blessed with the highest solar insolation. However, solar energy has not been fulfilled yet, predominantly in the field of the agricultural sector, where irrigation is still being done by outdated conventional methods. This paper focuses on the development of strategies to enhance solar energy use in the agriculture sector of Rajasthan state India. An intensive survey was being conducted among scientists, academicians, farmers, and government officials regarding the know-how of present policies and schemes for the different applications of solar energy in Rajasthan state India. The survey reveals that not only the farmers and rural persons but the intellectual world is also unaware of the different policies of solar program prevailing in the state. Based on the survey, various strategies have been suggested to accelerate the solar program among the rural and agriculture sectors of Rajasthan state India.

A traffic signal system established due to the congestion of vehicles at road intersections. Traffic choking at road convergence becomes a controversy for daily riders and proportionally allowing the violation of traffic rules or other hazards. The conventional traffic signal system has lots of disadvantages. Even the system is automatic but due to fixed time range it gives rise to other problem like traffic violation, air pollution indirectly this would lead to deceitful affair. The signal system has been executed using different types of controller some have fast execution time, a greater number of inputs and outputs, reliability also plays an important role in traffic signal system design. To overcome such issues, we proposed a design in this paper which works on the compactness of vehicles on traffic signals and also detects the traffic signal breach done by the vehicles. This paper shows the simulation of dynamic traffic signal and traffic breach control system with IR sensor or piezo sensor to detect the density of vehicles and traffic breach or jumping of red light. This paper related with an FPGA controller as a VLSI design using Verilog in Xilinx software.

An Electrical vehicle can utilize a force move framework to charge the on-board Rechargeable Energy Storage System (RESS the battery) or to give the capacity to the electric engine. It is additionally conceivable to utilize remote force move to charge the batteries while fixed, using charging pads. Both of these arrangements are satisfactory for assessing at home or in-vehicle parking, yet at the same time, require the vehicle to stop in a proper area to charge the battery. We propose an eco-friendly wireless charging system for electric vehicles, which enables wireless charging of the vehicle while running on the highways. The proposed approach is also used for the charging of cars in the shopping malls and other parking places. Moreover, the proposed charging system may require electrical energy from the solar PV systems and wind turbines, installed along the highways. The solar PV system and wind turbines are connected to form a Microgrid system and feed generated electrical energy to the wireless charging system. The surplus electrical energy may be either fed back to the primary grid or used for highway illumination. The wireless charging system also consists of an air-core transformer with its primary winding below the highway surface and secondary mounted on the vehicle. The ac power from secondary passes through a rectifier and dc-dc conversion stage to produce suitable dc voltage and current for the charging of the battery unit.
