Wireless Chatting Using RF Abstract

             In WIRELESS CHATTING USING RF  project we are sending a message to the RF receiver through RF transmitter using SMS keypad. The use of SMS keypad is to create a message which is to be transmitted from the RF transmitter to the RF receiver. 

            We are generating a message using SMS keypad which is to be send messages with the help of Microcontroller. As soon as the RF transmitter transmits messages they are displayed on LCD screen. A 433MHZ frequency carrier signal is generated by RF transmitter which is send using antenna. The message that was transmitted by the antenna at the transmitter side is received by the antenna at the receiver side, received message is taken by RF receiver which works on TLP434A transmitter at a frequency range of 433.92MHZ.The resulted message from the RF receiver is received by the microcontroller serially. The message is decoded and displayed on the LCD at the receiver side. 

            This can be used as an application for broadcasting the messages wirelessly ; it can be used in remote areas and industries where there is a continuous need of information to be transferred; it can be developed so as to control any type of appliances remotely.

Super Intelligent Robot Using Smoke Sensor and Light Projects Abstract

AIM:

Super intelligent robot using smoke sensor and light projects main idea is to develop a robot application which can direct its path automatically based on light.

Description:

            In this project TCS230 is the color sensor, which senses color intensity and converts into frequency with 50% duty cycle Square waveform. Measurement of frequency is done using micro controller. This sensor is having internally 3 filters and is programmable, to select desired filter. By this we can get selected compositions of the irradiant light. By using this sensor we can find color of the object.

There are two other sensors used in this application mainly light sensing and smoke sensing. Light sensor is used to display color that falls on LDR surface and display color information on LCD display. And the other sensor smoke sensor is used to detect smoke and microcontroller will set alarm. 

Procedure:

            The LDR color sensor can directly interface with the microcontroller. If this color sensor is irradiant with any color, it produces 3 different frequency outputs to the microcontroller by selecting the respective RGB filters present in it. Then microcontroller calculates HUE % value with these three composition values. According to this calculated HUE value microcontroller displays that color name.

Modern Home Automation using GSM Module project explains in detail about how to control home hardware applications like washing machine …etc remotely by using GSM technology messaging feature. This application mainly depends on cellular technology that too GSM technology, this project uses only messaging feature to control home appliances remotely.  Mobile communication is the technology used to connect microcontroller with a max232 which is a TTL converter.

Hardware applications in home network are connected with microcontroller which communicates with GSM using serial port communication. When user sends message from his mobile microcontroller will receive message and display it on LCD screen and based on that input it will on or off the system.

IR and RF communications are limited to a certain area where GSM can be operated from any where in the world to control the appliances. So, this GSM communication is better, secure and user friendly. This total method mainly depends on GSM system so users should maintain GSM signal strength and microcontroller should accurately receive signal and messages then the process will be fast and easy.

Applications for this are Industries with heavy parameters to handle, complicated areas where we can’t monitor the conditions manually; these are Now-a-days used in all kind of industrial and commercial complexes.

Fire Sensing and Control Robotics Project

AIM:

 The main aim of FIRE SENSING AND CONTROL Robotics project is to detect the fire and fire using smoke detection sensor.

The temperature sensor values are given input to the microcontroller. Microcontroller reads the values from temperature sensor, whenever the temperature exceeds the set point microcontroller gives a buzzer as a fire alert. And we can change sensitivity using a variable resistor. Apart from temperature sensor we are also using a smoke sensor. So here we are not only monitoring the temperature and also smoke, for this smoke sensor also we are going to connect a variable resistor, by using this we can change the sensitivity. When ever the values from smoke sensor exceeds the set point microcontroller will give buzzer alert.

The main advantage is using this we can provide safety for objects. The applications are in Industrial areas, hotel environments, factory environments and in costly environments.
