List of "8051 based Microcontroller Projects"

The most important problems faced are the misusage of electricity and its wastage. Sometimes due to carelessness of the authorities and the workers lamps are left ON which results in wastage of electricity. Water wastage is another problem which needs to be dealt with. Our project helps to overcome all these problems.
Firstly the Microcontroller around 4.00pm switches on the water supply once to water the entire garden few hours before opening of the garden for public. Next the gate is opened by running the motor which is driven by a motor driver operated by the Microcontroller. At around 6.00pm the lights are switched on depending upon the output of the LDR and the lights remain functional till the garden remains open for visitors.

Use of automated system for car parking monitoring will reduce the human efforts. Display unit is installed on entrance of parking lot which will show LEDs for all Parking slot and for all parking lanes. Empty slot will be indicated by glowing the respective LED.

Electrical appliances are controlled by the microcontroller using the previously set time.

This project which will consist of two basis modules. First is "Data Monitoring" & other is "Data Storage" A display unit will show the value of parameters. This will help for the person to know the values, for this purpose we are going to use various sensors, which will be connected to ADC. The other module is named as parameter storage. It can be used to store the parameter values in the memory. We are going to use EEPROM memory IC. These values can later seen using a keypad provided on the front panel. This system is useful as many times its difficult to measure the parameter values manually and also this module is more accurate than the domestic system.

Incubators are attracting interest from the medical profession. They are glass and metal cases heated to certain Humidity, into which enough air is admitted to maintain life. Until such time as infant is strong enough for Humidity of room. In baby incubator Humidity control is very important. And therefore we are controlling the Humidity according to our requirements. Humidity controller can be done by using Electronic circuit, Microprocessor & microcontroller. Now microcontroller is advanced among all above circuits therefore we are using Microcontroller for Humidity controlling of baby incubator

Main concept behind this project is to measure and display the number of persons entering in any room like seminar hall, conference room. LCD display placed outside the room displays this value. And when number of persons inside the room are zero, power supply inside the room can be cut using a relay interface. Second part of project serves the functionality of a door-latch opening using a password entered through keypad. As well as sending this data to a computer through serial port. This module also turn on buzzer if 3 wrong passowords are entered consequently. User can change this password anytime he/she wish using a keypad.

This project is used to measure the various parameters like Temperature and Light and display them on a LCD. Temperature and light is sensed by respective sensors and sensor output is ampilfied and given to ADC. Microcontroller controlls these parameters and keep them at some predefined levels using realy interface. These relays can be connected to Fan/Heater. At the same time these values of temperature and light to a computer through serial port.

This project can be used for Advertising or for providing information at various places like shops, government offices, hospitals, railway stations. The Rolling display is prepared using 5 X 7 Matrix LEDs which means LEDs are arranged in a pattern consisting of 5 columns and 7 rows. A matrix of 5 X 7 LEDs contribute to a single character. Here we have used 6 characters which means 6 matrices. The actual physical diamension of single matrix is 10 cm by 8 cm, so diamension of complete display is 10 cm by 48 cm. A keypad used to select which message has to be displayed. These messages are stored in a EEPROM. PC interfacing is used for sending data to computer.

Home security system project consist of three basic modules. First is IR transmitter and receiver module which works for the safety of doors at night or in case we are out of home. When the IR sensors are interrupted, a buzzer if turned on indicating someone is entered into house. LPG gas sensor is provided to detect the LPG Gas leakage. A buzzer is turned on when Gas is detected by the sensor. Third part of project serves the functionality of a door-latch opening using a password entered through keypad. This module also turns on buzzer if 3 wrong passwords are entered consequently. Data from all modules is sent to a computer through serial port

Set the interval time and buzzer time through keypad. An internal clock will run inside the controller which will turn on the buzzer at the desired time periods. PC interface is provided so as to send the data to the computer.

This project is used to measure the water level in a dam, after a particular time interval and to store them it into a memory IC for the sake of records. Later a person can access the memory using this project and see the previous records using a keypad and LCD. This data can be sent to a computer through serial port.

Main concept behind this project is of a door-latch opening using a password entered through keypad. As well as sending this data to a computer through serial port. User can change this password anytime he/she wish using a keypad
