    AC DIMMER OF TWO LOADS USING SINGLE CONTROLLER

    8,300.00 5,500.00

    This project is intended to attain AC dimmer of two loads using single controller. It is a renowned and aged technique of managing AC power, principally across linear loads for instance heaters brought into play in electric oven.
    In this project, we are using a comparator for zero crossing detection which is fed as an interrupt to the arduino UNO3. Here, the arduino delivers the output based on the interrupt received as the reference for generating triggering pulses. Using these pulses, we drive the Opto-isolators for triggering the TRIAC to achieve integral cycle control as per the input switches interfaced to the arduino. In place of a linear load to be used in the output, a series motor or lamp can be used to verify the output. A lamp is provided in this project in place of a motor for demonstration purpose. The project output with a lamp appears to be a simple project of lamp flickering but the real objective is to verify in a CRO/DSO ,whether at the random switching also the load switches on at zero cross of the waveform or not.

    AC DIMMER TO CONTROL AC VOLTAGE, SPEED OF INDUCTION MOTOR OR HEATER COIL

    4,400.00 3,400.00

    A voltage controller, also called an AC voltage controller or AC regulator is an electronic module based on either thyristors, TRIACs, SCRs or IGBTs, which converts a fixed voltage, fixed frequency alternating current (AC) electrical input supply to obtain variable voltage in output delivered to a resistive load.

    Induction motor speed control is done by varying the frequency of the applied voltage. Raising or lowering the voltage can have some speed control effects but these will be small, difficult to control, load-dependent, possibly cause the motor to overheat and, are not generally recommended.

    ACPWM power control using 555IC and IGBT

    4,100.00 3,200.00

    This 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 555 astable multivibrator. 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.

    ADVANCE CAR JACK CONTROLLED BY RF WIRELESS DEVICE

    17,600.00 14,000.00

    The project is designed to control the direction of car jack by using a RF technology for remote operation with a transmitter and receiver. The direction of the DC motor is depending on signal which is coming from transmitter. Hence, if the relay 1 & relay 4 gets ON then the motor rotates in forward direction. And if relay 2 & relay 3 gets ON then the motor rotates in backward direction.

    ADVANCE GREEN HOUSE WITHOUT MICROCONTROLLER

    7,100.00 5,800.00

    This project is designed to monitor the green house using Comparator IC. Various sensors are used to monitor the system. The sensors used are Rain sensor, Soil moisture sensor, LDR, wired security sensor, water level indicator, IR sensor. When the soil of the green house becomes dry the pump will turn on through which the water is let into the soil and the soil regains its moisture. While supplying the water to the dry soil the water level in tank will be reducing simultaneously which will be indicated by the LED’s.
    So when the water level reduces below the threshold level the pump will off automatically to avoid dry run.

    ANDROID CONTROLLED CAR JACK

    17,600.00 14,000.00

    The project is designed to control the direction of car jack by using an android phone with the help of Bluetooth device. The direction of the DC motor is depending on the signal which is coming from mobile. Hence, if we press UP, this is present on your mobile then the relay 1 & relay 4 gets ON, so the motor rotates in forward direction. And if when we press DOWN from mobile the relay 2 & relay 3 gets ON then the motor rotates in backward direction.

    ARDUINO BASED UNDERGROUND CABLE FAULT DETECTION

    6,200.00 4,700.00

    The objective of this project is to determine the distance of underground cable fault from base station in kilometers USING AN Arduino board. The underground cable system is a common practice followed in many urban areas. While a fault occurs for some reason, at that time the repairing process related to that particular cable is difficult due to not knowing the exact location of the cable fault. The proposed system is to find the exact location of the fault.

    AUTO POWER SUPPLY CONTROL FROM 4 DIFFERENT SOURCES

    4,900.00 3,700.00

    The main objective of this project is to provide uninterrupted power supply to a load, by selecting the supply source automatically from any available one out of 4 such as: mains, generator, inverter and solar in the absence of power supply. The demand for electricity is increasing every day and frequent power cut is causing many problem in various areas like industries, hospitals and houses. An alternative arrangement for power source is thus desirable.

    AUTOMATIC IDENTIFICATION OF ELECTRICITY THEFT

    10,000.00 6,000.00

    In proposed system automatic identification of electricity theft using arduino. If we implement the project for a complete network of a area which will be consuming a very huge amount of energy. Here we are using arduino board, LCD display, current sensor, buzzer. And here in this project we can calculate the energy or power transmitted by the KEB and the energy consumed by the network of area. If both transmitted power by the KEB and the consumed power by the area differ by a large value the arduino will display these difference in the power reading on the LCD and the buzzer located in the KEB starts beeping indicating theft of electricity. As total Power losses equals transmission power losses plus distribution power losses.
