AC DIMMER TO CONTROL AC VOLTAGE, SPEED OF INDUCTION MOTOR OR HEATER COIL
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.
AUTOMATIC POWER FACTOR CORRECTION USING PIC- MICROCONTROLLER
In this proposed system, two zero crossing detectors are used for detecting zero crossing of voltage and current. The project is designed to minimize penalty for industrial units using automatic power factor correction unit. The PIC microcontroller used in this project .
The time lag between the zero-voltage pulse and zero-current pulse is duly generated by suitable operational amplifier circuits in comparator mode is fed to two interrupt pins of a microcontroller. The program takes over to actuate appropriate number of relays from its output to bring shunt capacitors into load circuit to get the power factor till it reaches near unity.
Automatic Street Light Intensity Control Based On The IR Sensor Using Arduino
Nowadays the amount of power consumed by lighting and streets shares a major energy demand. The vehicles are passing over always and a part of places will be consisting of less dense areas and even no vehicle moments itself in few areas. But during the night all street lights will be on in a conventional street lighting system. To overcome this issue, proper energy-saving methods and lighting control are to be implemented.
Autonomous Fire Fighting Robot Using Arduino
A fire outbreak is a hazardous activity that leads to numerous consequences. Detecting a fire at an early stage and extinguishing it can aid in the prevention of various accidents. Till now we rely on human resources. This often leads to risking the life of that person. Therefore, fire security becomes an important aspect to save human lives. In this, a fire extinguishing robot has been proposed and designed which detects the fire location and extinguishes the fire by using sprinklers on triggering the pump. This robot uses flame sensors for accurate fire detection. This proposed model of Fire Extinguishing Robot using Arduino is used to detect the presence of fire and extinguish it automatically without any human interference. It contains gear motors and motor drivers to control the movement of the robot when it detects any presence of fire and will automatically start the water pump to extinguish that fire breakout. This model robot has a water ejector which is capable of ejecting water at the fire breakout place. The water ejector pipe can be moved in the required direction using a servo motor. The whole operation is controlled by an Arduino UNO.
Fire-fighting is an important but dangerous occupation. A firefighter must be able to reach the situation quickly and safely extinguish the fire, preventing further damage and reducing fatalities. Technology has come to rescue this issue, fire-fighters and machines are now having more efficient and effective methods of fire fighting. This gives you the design idea of a fire-fighting robot using autonomous operation. The robotic vehicle is loaded with a fire extinguisher and a water pump which is controlled over the solenoid valve to throw water. An Arduino UNO is used for the desired operation. A water tank and fire extinguisher set up along with a water pump are mounted on the robot body and its operation is carried out from the output through the appropriate signal from the sensor. The whole operation is controlled by an Arduino UNO.
Camera Surveillance Robot Using DTMF Technology
The “DTMF-based robot” is controlled by a mobile phone that makes a call to another mobile phone attached to the robot. In the course of a call, if any button is pressed, a tone corresponding to the button pressed is heard at the other end of the call.
This tone is called “Dual Tone Multiple-Frequency” (DTMF) tone. The robot perceives this DTMF tone with the help of the phone stacked on the robot. The received tone is processed by the ARDUINO with the help of an IC. The ARDUINO then transmits the signal to the motor driver ICs to operate the motors. Since this robot is controlled by dialing a call so we can also call it a DTMF-controlled robot.
The transmitter section consists of another phone with a smartphone through an app called..Using a mobile phone we can generate DTMF tones which will be received by another mobile phone mounted on a robot after call connection.
The mobile phone on the robot is connected to the Arduino controller and the output or Arduino is connected to the motor driver which helps the robot to move wirelessly.
As we are using the internet the robot can be operated from any part of the world so, we need to see where the robot is moving, for which we are using the Airdroid app for monitoring through a camera inbuilt into the smartphone mounted on the robot.
Diesal Generator Body Leakage Current Measurment And Auto Switching Based On Leakage Current
The emergency diesel generators in a nuclear power plant have an important safety function-supplying emergency electrical power to maintain cooling and other vital functions. The research reviewed in this article addresses the safety implications of aging of these emergency diesel generators and the influence of aging on their reliability. Historical operational information was assembled on component and system failures and their causes. One significant research result is that the fast-starting and fast-loading test procedure mandated by Regulatory Guide 1.108 and the standard Technical Specifications has contributed to wear and degradation. Other equally important aging and degradation factors for the diesel generators are identified and reviewed. A new approach developed represents a more balanced aging management program that includes (1) slow-start testing during which operating parameters are monitored.
(2) Analysis of data trends,
This approach should improve safety by identifying aging degradation that leads to fitture diesel generator failures. Timely maintenance could then prev*ent actualJafiures.

This information will be checked by the database server.
FOUR QUADRANT DC MOTAR SPEED CONTROL USING GSM
In this project, we are varying the speed of the DC motor (BLDC motor) by GSM sim 800 for transmitting the message for variation of speed (increasing or decreasing) using the Arduino Uno microcontroller using embedded C-programming. In various industries, the DC motor is found very common as its properties are very found in industrial applications such as high efficiency, high torque ratio, reliability.it is hard to operate in industries as it requires high maintenance that’s why we are using gsm sim to vary its speed as it’s very profitable and we can operate from long distance.
