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
$164.67$152.65These 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.

SOLAR GRASS CUTTER WITH OBSTACLE AVOIDANCE WITH SPRAY
$175.49$163.47Agriculture is demographically the broadest economic sector and plays a significant role in the overall economy of India. For the growth of Indian economy, mechanization is necessary. The main purpose of mechanization in agriculture is to improve the overall productivity and production. The system control is done by the Arduino UNO R3. Automation is achieved by using sensors and Arduino UNO R3.

SOLAR GRASS CUTTER WITH SPRAY
$168.28$156.26We present an Arduino-based automatic robotic system that is used for cutting grass or
lawns, mostly healthy grass which needs to be cut neatly like in a public park or a private
garden. The purpose of this proposed project is to design a programmable automatic pattern
design grass cutting robot with solar power which no longer requires time-consuming manual
grass-cutting and that can be operated wirelessly using an Android Smartphone via
Bluetooth from a safe distance which is capable of cutting the grass in indeed required shapes
and patterns; the cutting blade can also be adjusted to maintain the different lengths of the
grass. The main focus was to design a prototype that can work with a little or no Physical
user interaction. -
Solar Power Vaccine Storage Refrigerator
$156.26$141.84Large areas of many developing countries have no grid electricity. This is a serious challenge that threatens the continuity of the vaccine cold chain. The main alternatives to electrically powered refrigerators available for many years—kerosene- and gas-driven refrigerators—are plagued by problems with gas supply interruptions, low efficiency, poor temperature control, and frequent maintenance needs. There are currently no kerosene- or gas-driven refrigerators that qualify under the minimum standards established by the World Health Organization (WHO) Performance, Quality, and Safety (PQS) system.

Speed Control Of Induction Motor Using Firing Angle Control
$90.15$70.92The main object of this project is to develop speed control of two induction motor using firing angle control system which is helpful to control the speed of an induction motor using microcontroller
In this project, the zero-crossing point of the voltage waveform is detected by a comparator whose output is then fed to the microcontroller. Then, it provides the required delayed triggering pulses to a pair of TRIAC through an opto-isolator connected to this circuit. Finally, power is applied to the load through the TRIAC. Four push-button switches are interfaced to the controller for increasing and decreasing the AC power to the load. In this project, a lamp is used in the place of induction motor demonstration purposes. The motor speed variation depends on the power reduction.

STREET LIGHT THAT GLOWS ON DETECTING VEHICLE MOVEMENT
$90.15$60.10This project is designed to detect a vehicle movement on road to switch on only a block of street lights that are ahead of the vehicle, and to switch off the glowing lights when the vehicle passes away from the lights. This will help to save electrical energy.

SUBSTATION MONITORING OVER IOT
$126.21$105.78The purpose of this project is to acquire the remote electrical parameters like voltage, current and frequency and send these real time values over network along with temperature at power station. This project is also designed to protect the electrical circuitry by operating a relay.

SUPER / ULTRA FAST ELECTRIC CIRCUIT BREAKER
$75.73$43.27The project is designed to shut down a power supply when it is overloaded by using a super-fast electronic circuit breaker. The concept of electronic circuit breaker came into focus realizing that the conventional circuit breakers such as MCBs take longer time to trip. Therefore, for sensitive loads, it is very important to activate a tripping mechanism at the shortest possible time, preferably instantaneously.
