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.
ADVANCE GREEN HOUSE WITHOUT MICROCONTROLLER
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.
ADVANCED BUS WITH AUTOMATIC TICKETING, STUDENT PASS FACILITY, BALANCE CALCULATION AND SMS ALERT
The aim of this project is to implement advanced bus with automatic ticketing, student pass facility, balance calculation and SMS alert. This system is used for automatic ticket generation, student bus pass information as well as balance calculation for each ticket and balance, validity alert message on user’s mobile phones.
The most of people in India uses bus travelling facility in their daily routine life. The manual use of bus reservation is presently very troubled thing and also consumes a lot of time by having to stay on a long queue. For this reason, an efficient system is to be proposed in this project to ease the issue of bus ticketing within the country.
AUTOMATIC IRRIGATION SYSTEM ON SENSING SOIL MOISTURE CONTENT
The project is designed to develop an automatic irrigation system that switches a pump motor on or off upon sensing the moisture content of the soil. In the field of agriculture, use of proper method of irrigation is important. The advantage of using this method is to reduce human intervention and still ensure proper irrigation.
EARTHQUAKE DETECTION & IT’S MONITORING OVER IOT
In this processed system, we are monitoring the earthquake, if any vibration/ tilt of the earth’s surface takes place; the system will alert us and send the data over IOT page. So to avoid the life loss and economic loss we are developing this device.
In this project we are using Arduino board i.e. the heart of project, 2-vibrator sensor, 2-accelerometer, LCD display. An accelerometer is an electromechanical device used to measure acceleration forces and also for sensing vibrations in systems or for orientation applications. So when some orientation according to x-axis, y-axis or z-axis happens to the earth’s surface then it will display a message on LCD that there is Earthquake. And also sends data on IOT page through Wi-Fi module.
Finger Print Based Voting Machine
Fingerprint Voting System was implemented with the Arduino technology. In this System a voter can poll his vote easily. In this database server all voters’ information was stored to register in this system, the voter should fill a registration form with the help of a user id and password. This information will be checked by the database server.
Four Quadrant DC Motor Controls without Microcontroller
The main intention of this project is to control the speed of a DC motor in alternative directions using speed control unit and to operate the motor in four quadrants: ie, clockwise, counter clock-wise, forward brake and reverse brake
GSM & GPS BASED SOLDIER TRACKING & HEALTH MONITORING SYSTEM
Army is one of the most important aspects of any country. It is our duty to equip soldier with better advanced technology. In this proposed system, we are monitoring the soldier’s health parameters such as heart beat rate and body temperature continuously measured and transmitted wirelessly to the control room using GSM and also the exact location through GPS.
Here we are using voltage regulator circuit for power supply, Blood pressure & heartbeat sensor, MQ-7 sensor, temperature sensor, Wi-Fi module, GSM, GPS, buzzer and LCD display these are also the hardware parts of this projects. By using temperature sensor we can monitor the soldier’s body temperature. If smoke is detected due to fire air it is detected by using MQ-7 sensor. With the help of heartbeat & blood pressure sensor we can read the heartbeat & B.P respectively.
The project is designed to develop an half adder system that An adder is a digital logic circuit in electronics that implements addition of numbers. In many computers and other types of processors, adders are used to calculate addresses, Adders are classified into two types: half adder and full adder. The half adder circuit has two inputs: A and B, which add two input digits and generate a carry and sum.
HEARTBEAT MONITORING SYSTEM OVER IOT
In this proposed system, we are monitoring the patient’s heartbeat by using arduino board & heartbeat sensors. A technological innovation in the field of medical science has played a vital role in disease prevention and diagnostic. Heartbeat is an important health parameter that is related to the human cardiovascular system.
