This study implemented a hybrid net metering technology that will help limit the power consumed from the grid and maximize the usage of renewable energy, i.e., solar energy. The main objective of the study is to design a prototype on a small scale basis that controls and monitors the usage of power consumed by the load using a hybrid system. The development of hybrid system provided a significant...
This paper presents a design approach to an embedded monitoring system found in distributed renewable energy power systems. The grid connected distributed power system, delivers energy to the consumers located on the micro-grid, operating at distribution voltage levels, and also delivering the remaining surplus energy to the main distribution grid. The aim of this paper is to present the development...
Smart home is a house that uses Internet of Things(IoT) to monitor the environment, control the electric appliances and communicate with the outer world. Smart home is a complex technology, but a developing one. A smart home automation system has been developed primarily because in today's time and world, everybody's in a surge and wishes to screen and get to everything without being there physically...
Smart Switch allows switching almost any appliance ON and OFF remotely via local network or via internet. It is designed to receive start/stop commands and monitoring smart switch application like voltage, current and power. The paper presents a smart power switch system that can be controlled wirelessly or via internet, which has ability control power outlet and monitor electrical events such as...
The project aims at saving energy by detecting the vehicle movement on highways and switching on the block of street light ahead of it and simultaneously switching off the trailing lights. This project requires a sensor to detect the day and night and an array of piezoelectric sensors to detect the vehicle movements and accordingly switching on the lights ahead of it. So when there are no vehicles...
This paper presents development of a Wi-Fi smart plug which is able to switch on/off remotely electrical appliances connected. It also monitors their energy consumption. A web application is developed so that users may interface with the smart plug. A bi-stable (latching) relay is employed in the single phase in order to reach zero consumption of the relay coil when it is stable. Measurement accuracy...
Number of break-ins either in cars or houses are rising at an alarming rate. This cause problems to society in terms of loss of belongings or precious items and damages of the properties. This system is designed to help car users to protect their cars from such incidents with the use of alarm and GSM module. It focused on detection of movement inside the vehicle with sensor. An SMS is send to the...
The embedded system innovation has the close and indivisible relationship with the environment science aesthetics. This paper deals with a simple, easy to install, microcontroller-based circuit to monitor and record the value of temperature, humidity, soil moisture and sunlight of the natural environment that are continuously modified and controlled in order optimize them to achieve maximum plant...
The paper focuses on a type of generator sets, designing a generator set's monitoring detecting system, prototype circuit is designed, the serial communication between the MCU (Microcontroller Unit) and the PC (Personal Computer) is achieved, the anti jamming technology has been considered, and it uses VB (Visual Basic) to carry out the design of the background manager, the whole system is debugged.
In clinical applications, the liquid of high-pressure syringe sometimes leak out of vein due to rapid injection speed and high pressure. Based on Texas Instrument's microcontroller MSP430FG4619 and Measurement Specialties Inc's pressure sensor FS2050, designs a diversion and alarm system to prevent the leakage of high-pressure syringe. The system offers the real-time monitoring for the full injection...
A self-powered wireless ultrasonic flow sensor system has been designed and developed from a system level approach in this paper. By using small-sized hydroelectric generator as the source of power for commercial low power microcontrollers, energy harvesting circuitry, and GPRS transmitters, the sensor is capable of detecting water flow in water pipelines network. A major feature of this sensor system...
The existing data sampling schemes can not update ROM serial numbers of DS18B20 automatically and locate DS18B20s accurately. For these reasons above, it is difficult to replace the faulty DS18B20s immediately. To solve this problem, both I/O (Input/Output) ports number of MCU (Micro Controller Unit) and the value of temperature alarm trigger registers (TH and TL) are used to determine the storage...

This miner's lamp monitoring and control system is composed of a central control station and a number of miner's lamp charging nodes. The central control station of miner's lamp monitoring and control system is constructed with the embedded microcontrollers S3C2410A based on ARM9,...
A transfusion system faced to hospital is presented. The system has real-time monitoring and alarming (when there exit abnormal instance or the transfusion is completed) functions, which well settle the inconvenience of venous transfusion in clinic, and increase the security and efficiency. The Photoelectric sensor technology and signal processing technology are applied to acquire the reliable detection...
iMAT is a system of automatic medication dispensers and software tools. It is for people who take medications on long term basis at home to stay well and independent. The system helps its users to improve rigor in compliance by preventing misunderstanding of medication directions and making medication schedules more tolerant to tardiness and negligence. This paper presents an overview of the assumptions,...
A new kind of control system to remotely manage an LV switchboard is presented. The main feature of the system is an optimal load management that allows both to optimize end-use energy consumptions and increase the level of supply continuity. An interesting application of the switchboard lies in the management of LV installations connected to smart grids, where the consumer - also named “prosumer”-...
