Rf Remote Controal Home Appliances
$57.70$45.68This work presented here is to controlled independent home electrical appliances through RF based remotesystem. From any place without any line of sight around the house, RF based wireless remote control system can change the state of the electrical appliances either in on state or off state. The controlling circuit is built around RF transmitter and RF Receiver modules and decoder IC HT12D with few passive components.

RF REMOTE CONTROLLED FOUR QUADRANT DC MOTOR
$69.72$64.91The project is designed to develop a four-quadrant operation of the Dc motor remotely controlled by an RF Remote. This system could also be a really sustainable system for controlling the DC motor in four directions like clock-wise, counter-wise, reverse brake, and forward brake. It additionally features high-speed mode and low-speed mode in speed control.

SMART GRID WITH ENERGY MEASURMENT AND ELECTRICITY THEFT
$156.26$144.24Energy is a very important aspect of any household, industry, agriculture and so. Managing energy efficiency and conserving it intelligently for appliances is very much important. The energy usage is directly affected by Coal, oil, and so on power generation. Towards this, there has been a lot of research work carried out in developing some smart lighting systems pertaining to classrooms for conserving energy. In one another research, researchers have developed an Android-based Smart home system for monitoring the usage of power to avoid any kind of anomaly. In none of the research, researchers work towards automating the appliance control towards conserving the energy. Most of them concentrate on controlling the appliances using android devices. So with the upcoming of machine to machine communication where devices can be connected wirelessly leading to IoT, we here have developed an IoT based Smart Energy Management system where appliances like Fan and Bulb to start with are controlled wirelessly based on humidity and light intensity information. These inputs are used towards controlling the appliances intelligently rather than just switching them on or off. In addition, the system also keeps computing throughput the day power consumption of the appliances which gives the user knowledge of power being consumed over a period of time. These details are updated in the Cloud server. This prototype system developed has achieved energy conservation in every household
With the prevalence of the Internet of Things (IoT), smart meters have become one of the main components of smart city strategies. Smart energy meters generate large amounts of fine-grained data that are used to provide useful information to consumers and utility companies for decision-making. Nowadays, smart energy meter analytics systems consist of analytical algorithms that process massive amounts of data. These analytics algorithms require ample amounts of realistic data for testing and verification purposes. These energy meters will read the energy consumed and upload the data over the IoT page. Thus the data is stored over the web page permanently. Then add the theft as it is in a load then on the buzzer

SMOOTH OR SOFT START OF SINGLE PHASE INDUCTION MOTOR
$65.51$53.49The main intention of this project is to provide protection for a single-phase pump motor by applying initial voltage gradually from low to high for obtaining soft start. The pump motor draws more current than its rated capacity during their starting condition which may lead to the damage of the windings of the motor. In order to avoid this problem, applied voltage is gradually increased from low to high so that the soft start of the pump motor is performed.

SOFT START OF INDUCTION MOTOR USING ACPWM
$100.97$69.72This project attempts a soft start control technique for the single-phase a.c. induction motor. The circuit operation is controlled by an 8051 family microcontroller. The drive uses a PWM controlled MOSFET and the load in series with a bridge rectifier. The device attempted here takes advantage of both the low price of the phase angle control and the low harmonic content and high efficiency that we can get with standard converter topology.

Soft Start of Three Phase Induction Motor
$96.16$91.35The project is designed to provide a soft and smooth start to a 3 phase induction motor. The three phase induction motor during the initial starting condition draws up much higher current than its capacity and the motor instantly reaches the full speed. This results in a mechanical jerk and high electrical stress on the windings of the motor.

SOLAR GRASS CUTTER WITH OBSTACLE AVOIDANCE
$200.73$188.71These days we are facing the problems like pollution, power cut problem, etc. In order to overcome these problems, we have thought about the device, which can be performing its functions without causing any of these problems. So we have thought of doing the project on cutting grass, which uses renewable sources of energy for its operation like solar energy.
