BIOMEDICAL MONITORING SYSTEM (AT89C2051 + TX/RX)
In spite of the improvement of communication link and despite all progress in advanced communication technologies, there are still very few functioning commercial wireless monitoring systems, which are most off-line, and there are still a number of issues to deal with.
Therefore, there is a strong need for investigating the possibility of design and implementation of an interactive real-time wireless communication system. In our project, a generic real-time wireless communication system was designed and developed for short and long term remote patient-monitoring applying wireless protocol. The primary function of this system is to monitor the temperature and Heart Beat of the Patient and the Data collected by the sensors are sent to the Microcontroller. The Microcontroller transmits the data over the air.
At the receiving end a receiver is used to receive the data and it is decoded and fed to Microcontroller, which is then displayed over the LCD display. If there is a dangerous change in patient's status an alarm is also sounded.
The chip tester verifies the functionality and timing of a variety of 7400 series integrated circuits. Students taking Digital Logic Design Lab, Use these chips often in their laboratory.
The IC to be tested should be placed on the ZIF socket and the Microcontroller prompts the user to enter the IC number of the chip to be tested. After entering it the microcontroller will check the IC as per the truth table of the IC which is stored in its ROM. It will check each aand every pin of the IC and produce the Output detaily. Like "Gate 1 is good", "Gate is Bad", "Counter 1 is Good" etc
The Block diagram of the project is given below for reference
Device control through Bluetooth from Symbian OS Mobiles
Use your Symbian OS mobiles to control devices through Bluetooth.
The serial to Bluetooth converter from sparkfun.com is used in this project.
The Microcontroller At89C2051 is used to receive the data from the mobile through bluetooth.
Most of the Nokia smartphones can be used in this project.
There is an another design with AUBTM-22 Bluetooth module
Now-a-days Electronic voting machines are being used effectively. The confidence of the voter in its flawless working is gradually building up and these machines are thus becoming quite popular throughout the country.
Features of the electronic voting machine include avoidance of invalid votes and reduction of counting time and the consequent expenditure incurred on manpower deployment. By using the Microcontroller the voting machine can be built up easily and it will make simple to operate
The need for a device that can detect and extinguish a fire on its own is long past due. Many house fires originate when someone is either sleeping or not home. With the invention of such a device, people and property can be saved at a much higher rate with relatively minimal damage caused by the fire. Our task as electrical engineers was to design and build a prototype system that could autonomously detect and extinguish a fire. Also aims at minimizing air pollution.In this Project we design a Fuzzy based Microcontroller controlled Robot.
Automatic Room light Controller with Visitor Counter (AT89S52)
This Project “Automatic Room Light Controller with Visitor Counter using Microcontroller� is a reliable circuit that takes over the task of controlling the room lights as well us counting number of persons/ visitors in the room very accurately. When somebody enters into the room then the counter is incremented by one and the light in the room will be switched ON and when any one leaves the room then the counter is decremented by one. The light will be only switched OFF until all the persons in the room go out. The total number of persons inside the room is also displayed on the seven segment displays.
The microcontroller does the above job. It receives the signals from the sensors, and this signal is operated under the control of software which is stored in ROM. Microcontroller AT89S52 continuously monitor the Infrared Receivers, When any object pass through the IR Receiver's then the IR Rays falling on the receiver’s are obstructed , this obstruction is sensed by the Microcontroller
Auto Control of three phase Induction motor (AT89S52)
This Project can be used with the three phase Induction motors. The circuit will take the full control of the motor and it will protect the motor from several faults such us over voltage and under voltage and the circuit will switch on the motor under safety conditions.
The circuit was fully controlled by the microcontroller and the microcontroller will continuously monitors the voltages of the three phase and if the voltage goes abnormal then it will switch off the motor until they are normal. All the conditions are displayed it over the LCD display. In our project we are using the popular 8 bit microcontroller AT89S52. It is a 40 pin microcontroller.
