Multiuser SMS Based Wireless Electronic Notice Board Project represents the model to show the notices on technological notice board in colleges through sending messages in the form of SMS by mobile.

The hardware includes microcontroller AT89s52, the microcontroller is blend with converter MAX232 level and GSM Modem. The hardware also includes 64K EEPROM chip AT24C64 and includes the actual time clock DS1307 to sustain the time track. The LED display is connected to microcontroller to display notifications.

Microcontroller coding would be accomplished with the help of Keil and Embedded C. Many customers are authenticated to update the notices over the technological notice board by giving password with the help of wireless communication.

Freeway Traffic Mechanism for Emergency Vehicles

These days’ traffic congestion is the biggest problem of densely populated cities. The project focuses mainly on three areas - priority mechanism for emergency vehicles like Ambulances, Fire Engines to control the traffic density for their smooth passage and monitoring the traffic junction. This project is a replica of a four way lane crossing in real time scenario. The project proposes primarily the problems faced by emergency vehicles. RFID concept is used to make green for the Ambulances lane and thus providing a stoppage free way for the Ambulance.

The secondary, importance is given to controlling the traffic density by placing IR sensors used to measure the density of vehicles which are fixed at a fixed distance. If the traffic density is high on particular side, more priority is given for the side where the vehicular traffic is more and green signal is given to this side of the traffic. By using this system traffic can be cleared without irregularities and time delays. A Wireless camera is used to monitor the vehicular traffic time and also monitor the problems which might occur at the junction. A specific allocation of time is given way for smooth passage for pedestrians. 

Now a day’s everyone needs a device which could control appliances wirelessly. This makes us to operate them on our fingertips from particular vicinity with ease.This time I have done something like this, I have created a prototype of a device which controls 4 devices/appliances separately using RF (Radio Frequency) technology. The device comprises of two sections: Transmitting (remote) and Receiving part. The transmitting part works as a remote device to send the corresponding data to the receiver section. It further consists of 4 SPDT (single pole double throw) switch, one Encoder IC (HT12E) and a TX module (433 MHz). These 4 switches are connected to the 4 data pins of the encoder IC to generate a 4-bit data to be transmitted. The switches provide either high (+5V) or low (0V) signal levels.
