SPEED CONTROL OF INDUCTION MOTOR USING ACPWM
₹8,400.00₹7,400.00This project attempts a new speed control technique for the single-phase a.c. induction motor. It presents a design of a low-cost; high-efficiency drive capable of supplying a single-phase a.c. induction motor with a PWM modulated sinusoidal voltage. The circuit operation is controlled by an 8051 family microcontroller.

Speed Control Of Induction Motor Using Firing Angle Control
₹7,500.00₹5,900.00The 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.

SPEED CONTROL OF TWO INDUCTION MOTOR USING ACPWM
₹10,500.00₹8,600.00This project attempts a new speed control technique for the single-phase a.c. induction motor. It presents a design of a low-cost; high-efficiency drive capable of supplying a single-phase a.c. induction motor with a PWM modulated sinusoidal voltage. The circuit operation is controlled by an 8051 family microcontroller. The device is aimed at substituting the commonly used triac phase angle control drives. The circuit is capable of supplying a single-phase a.c. induction motor (or general a.c. inductive/resistive load) with varying a.c. voltage. The same as in triac control, the voltage applied to the load can be varied from zero to maximum value. On the other hand, it uses a pulse width modulation technique (PWM), and when compared with the phase angle control used for triacs, produces much lower high order harmonics.

STREET LIGHT THAT GLOWS ON DETECTING VEHICLE MOVEMENT
₹7,500.00₹5,000.00This 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.

SUN TRACKING SOLAR PANEL
₹7,500.00₹5,000.00This project employs a solar panel mounted to a time-programmed stepper motor to track the sun so that maximum sun light is made incident upon the panel at any given time of the day. This is better compared to the light-sensing method that may not be accurate always – for example, during cloudy days.

Sun Tracking Solar Panel
₹13,000.00₹12,000.00In this project, LDR’s are working as light detectors. Before we go into detail, we will have to understand how the LDR’s work. LDR (Light Dependent Resistor) also known as photo resistor is the light sensitive device. Its resistance decrease when the light falls on it and that’s why it is frequently used in Dark or Light Detector Circuit. Check the various circuits based on LDR here.

SUPER FAST ELECTRONIC CIRCUIT BREAKER
₹7,500.00₹5,000.00The 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.

Transformer Health Monitoring
₹7,350.00₹6,350.00Transformers are a vital part of the transmission and distribution system. Monitoring transformers for problems before they occur can prevent faults that are costly to repair and result in a loss of service. The performance of prototype model developed is tested at laboratory for monitoring various parameters like transformer Over voltage and Under Voltage, Over current and Under current, Over temperature etc.

Transformer Health Monitoring Using GSM
₹10,500.00₹6,800.00Transformers are a vital part of the transmission and distribution system. Monitoring transformers for problems before they occur can prevent faults that are costly to repair and result in a loss of service. Current systems can provide information about the state of a transformer, but are either offline or very expensive to implement. This project objective is to develop low cost solution for monitoring health condition of remotely located distribution transformers using GSM technology to preent premature failure of distribution transformers and improving reliability of services to the customers. An Embedded based hardware design is developed to acquire data from electrical sensing system. It consists of a sensing system, signal conditioning electronic circuits, advanced embedded hardware for middle level computing, a powerful computer network for further transmission of data to various places.

ULTRASONIC BASE LIQUID LEVEL MEASURMENT
₹6,500.00₹5,800.00This report details the implementation of liquid level measurement system using ultrasonic waves. As the human ear audible range is in between 20 Hz to 20 kHz, it is insensitive to ultrasonic waves that falls beyond that range, and hence, the ultrasound waves can be used for applications in industries or vehicles without hindering human activity. They are widely used as range meters and proximity detectors in industries and also in the parking assistance systems.
