AIM:            The main aim of Automatic Humidity Monitoring And Pumping System For Farmers project is to monitor and record the values of humidity of natural environment and to pump the plants water at required humidity level in order to achieve maximum plant growth and yield.This projects main intention is to develop a application where it can collect data about soil conditions with a low cost equipment and less labour involved.

DESCRIPTION:   In this project embedded micro controller is used with a c program written inside it using a Keil IDE software, using this system it will be easy to record and monitor important parameters like humidity, temperature of the natural environment that is continuously modified and controlled in order optimize it to achieve maximum plant growth and yield. The controller used is a low power, cost efficient chip manufactured by ATMEL having 4K bytes of on-chip flash memory. It communicates with the humidity sensor module in real-time in order to control the humidity process.

There is one water level sensor is present to indicate the level of water in the well. Also, the use of easily available components reduces the manufacturing and maintenance costs.

AIM:            The main aim of Digital Energy Meter With Auto Limiting Of Load System project is to implement the digital ENERGY METER with overload protection capability by continuously measuring the voltage and current values.  The purpose of the project is to provide an automation system for the automatic load limiting of digital energy meter with reference to the current and voltage values.

Initially we will work on the implementation of a regular watt hour reading meter using micro controller. In this discussion we will cover how ADC can be used for measuring both voltage and load current accurately without errors. Micro controller used in this project will measure parameters like rms voltage and current, kWh which will be displayed on LCD.All metered data is securely stored as it is updated in a nonvolatile memory (EEPROM). The design discussed here uses two Current Transformers (CTs) for current sensing.. The second part of this project is to implement auto limiting of load. That means when over load is occurred we have to trip the incoming supply. For that purpose we are going to place a relay circuit and when over current is occurred microcontroller will detect that and controller will activate the buzzer.

AIM:      The main aim of  Optimal Voltage Change Indicator For Mobile Through Solar System project is to design an equipment which is used for charging a mobile phone by using solar panel. 

DESCRIPTION:                  The main objective of this project is to charge a mobile by using solar panel. The block diagram mainly consists of a micro controller, analog to digital converter, a solar panel and  relay. So when voltage is obtained from the solar panel, it is given to the ADC. Here the solar panel keeps continuously generating voltage but to charge a mobile we need maximum voltage . maximum voltage is obtained only at maximum intensity. So when ever voltage is generated it is given to the ADC and  it is further sent to the micro controller. When voltage other than  maximum voltage is obtained the relay is operated and it gets tripped and when maximum voltage is obtained the mobile gets charged. Hence by using solar panel we can easily charge a mobile.

AIM:        The main aim of Designing Equipment For Substation Monitoring And Controlling project is to design equipment for monitoring and controlling a substation. The purpose of this project is to overcome the draw backs of over voltages, over currents, temperatures.

DESCRIPTION:                      In this project mainly we are using a micro controller, and an ADC. Here ADC is used for monitoring voltage, temperature and current. According to the set values which are fixed in micro controller, the voltage levels, current levels and temperature levels are monitored and these are controlled through microcontroller in such a way that if voltage is increased or decreased then the relay is operated that is  transformer is tripped. In the same way when temperature is increased the blower will on and when temperature is decreased the cooler is on. And all these values will be fed to the pc through serial port network.even this can be controlled manually through PC. Hence the substation is monitored and controlled.

Capacitor Bank Type Power Factor Control System Project AIM:

        The main aim of Capacitor Bank Type Power Factor Control System project is to design an equipment which controls the power factor by using a bank of capacitors. 

DESCRIPTION:

                     The block diagram mainly consists of a microcontroller, zero crossing detector, inductive load, capacitive load, zero crossing detector and capacitors. Here we are using bank of capacitors. Since these are bank of capacitors they are operated sequentially. There are two keys, key1 and key 2. When a key1 is pressed signal is sent to the microcontroller and inductive load is operated and relay is operated for resistive load and tripping occurs. In the inductive load the current is lagging because inductor always opposes the sudden change in current. In order to identify the inductive load here we are using choke. Hence when inductive load is operated the micro controller sends and the capacitors C1,C2and C3 are operated sequentially.

Here we are using a bank of capacitors. So depending up on the load the capacitors are made on. Say for eg when a large amount of load is dealt then all the capacitors are made ON. when a medium amount of load is dealt only two capacitors are made on and when small amount of load is dealt  only one capacitor is made ON. When key 2 is pressed resistive load is operated and relay is operated for inductive load and tripping occurs.When the resistive load is operated then the current is leading and hence it sends signal to the micro controller and the microcontroller sends signal further and the relay is operated and tripping occurs. Here in order to identify the resistive load  bulb is used. In alternating current, the zero-crossing is the instantaneous point at which there is no voltage present.

Mobile Operated Field Motor Control System Projects AIM:        The main aim of Mobile Operated Field Motor Control System project is to obtain field motor control  by mobile phone. 

DESCRIPTION:          The block diagram mainly consists of micro controller, opto coupler, triac and GSM modem. GSM modem consists of a sim card. When an sms is sent to the GSM modem the modem reads the sms and it is sent to the microcontroller. This project uses OPT coupler for finding out shortest path for optical signal transmission between the elements of the circuit mainly elements used in the project are transmitter and receiver, Before transmitting data electrical signals are converted to light beams transferred, then converted back to an electrical signal, there is no need for electrical connection between the source and destination circuits.

The microcontroller sends signsl to the optocoupler and it sends signal to the triac and the triac is triggered and hence the induction motor is controlled.

REMOTE  SOMKE TEMPERATURE DATA  ACQUISION SYSTEM PROJECTS AIM:

     The main aim Remote Smoke, Temperature Data Acquision System project is to design an equipment for acquision of data such as smoke, temperature  from remote places.

DESCRIPTION:

      Basically this is a PC based remote data aquision.this equipment is used to detect the smoke accumulated and temperature in remote areas. This block diagram mainly consists of a microcontroller,an ADC,serialport,and temperature and smoke sensors. When the sensors detect the smoke and temperature these are given to the analog to digital converter. Hear the data is converted in to digital format and these data is given to the microcontroller. The microcontroller sends this data to the serial port where the data is transferred serially and this data is then given to the PC. Hence by just simple circuit we can acquire data of remote places easily.
