Ac Motor Speed Control Using Power Triac with Display Unit

In this application we are developing a electronic equipment for AC Motor Speed Control Using Power Triac With Display Unit. Using this application it will be easy to control Speed of AC Motor switches. In this project we use array of switches for controlling motors. Each switch has its own functionality for controlling motors at different speeds. By using these switches variations of motor speed can be managed.

Basically AC motors need more current which is not provided by micro controller used in this project. So we use TRIAC driver for our driving AC Motor. Here we need to consider two factors , Firstly driving AC motor with low current and protecting micro controller from high current. In order to solve this problem here we are using MOC 3021. A 16X2 LCD for displaying the running motor speed.

Pc Based Substation Monitoring and Control System

PC Based Substation Monitoring And Control System Project explains about a system through which power efficiency can be increased with better decision system. This system is used by most of the electricity board around the country. Along with decision making this system will bring intangibles like safety to the system. Though there are many applications which is used for improving increasing power efficiency, but they are not as accurate as that of this application. This application had created a standard by providing customizability and availability of local technical support.

Using this application it will be easy for substations to monitor different parameters like voltage, current and temperature using various sensors and these readings are sent to micro controller through ADC. By analyzing these parameters regularly system will take decisions like shut down substations. This information will be sent to PC’s Hyper terminal using RS232 cable.

Fan Speed Control by RC5 TV Remote

Aim:The aim of Fan Speed Control By rc5 tv remote project is to control the fan speed using microcontroller with rc5 tv remote.By controlling the Thyristor firing angle control scheme. 

Principle: This is a phase angle control of a Triac. The 50 Hz or 60 Hz Sine wave of mains can be turned on at any point after the Zero Crossing. There are few methods which can control delivered loads one among them are phase control method is the best method. Technique used in this method works same as that of pulse width modulation and digital signal. This type of methods is mostly used in light dimmers. The light’s brightness will be proportional to the area under the curve. 

Hardware Description:

The block diagram of the fan speed control by controlling the thyristor firing angle method is shown in figure. 

TSOP1738 decoder is used to decode command signals received from TV remote ,this is already programmed microcontroller flash memory, sending to the optoisolator ,during the pulse high duration this can triggering the gate of the triac,so current is flowing in to the load, during pulse low duration ,current is not flowing into the load.so,by this method we can control the power delivered to the fan, hence the speed of the fan can be control.

Device Switching By Using the TV Remote System

Aim:The aim of Device Switching by Using The TV Remote System project is to controlling the device switching (i.e. ON or OFF) by using the using micro controller with TV remote.

 Hardware Description:The block diagram of the Device switching by using the TV remote method is shown in figure. As shown in the block diagram ,the main circuit is a combination of two sub circuits.

   1. Zero crossing detector circuit. 

   2. IR sensor(TSOP1738).

 After getting an interrupt 89C52will switch ON/OFF the device based on key pressed on TV remote. 

During power on condition all three devices are in OFF condition.When you press Key ‘1’ on TV remote device 1 switched on. Again when you press key ‘1’ on TV remote.

Device 1 switched off. When you press Key ‘2’ on TV remote device 2 switched on. Again when you press key ‘2’ on TV remote device 2 switched off. When you press.

Key ‘3’ on TV remote device 3 switched on. Again when you press key ‘3’ on TV remote Device 3 switched off. 

The user can press the TV remote, the TSOP1738 decode the command depending on the pressed key the control signal for the pressed key ,already programmed into the microcontroller flash memory, sending to the Buffer IC(Relay driver ULN2003) IC ,depending on the  controlling signal respective device is switched ON/OFF.

Digital Energy Meter with Auto Limiting Of Load System

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.

Intensity Control of Room System

AIM:      The main aim of Intensity Control Of Room System project is to design an equipment which controls the intensity of a room.

DESCRIPTION:                       The block diagram mainly consists of microcontroller, triac, and keys. The main concept behind this intensity control is gate width. The device is controlled based on the gate width. By pressing the keys the intensity control is obtained. When a key is pressed it gives signal to the microcontroller and the micro controller gives gate pulses to the triac. These gate width is obtained in the triac by triggering it at a certain firing angle. So when the HIGH key is pressed the triac is triggered at less firing angle and the gate width of the pulses is more hence the intensity of the device is increased. In the same way when the LOW key is pressed the triac is triggered at more firing angle and gate width of the pulses is decreased and hence the intensity of the device is decreased. Hence just by pressing HIGH and LOW keys the intensity of the bulb is controlled by using triac and microcontroller.

Optimal Voltage Change Indicator for Mobile through Solar System

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.
