10.                       BLACK BOX FOR VEHICLE

Lot of the time drivers drive above limit or over heat the engines thus decreasing the vehicles performance considerable. Moreover accidents occur due to over speeding & are on rise especially amongst the youngsters so parents need to keep a watch on them.  Black box for vehicle does the same it checks if the vehicle RPM is above limit & if so logs the RPM along with the time at which the speed limit has been crossed & the number of time the vehicle was above the speed limit. Moreover it checks the engine temperature & if the temperature is above limit a buzzer is sounded. The device is then connected to the PC where the speed logs can be seen.

Microcontroller (8951/8952) is the heart of the project, the controller gets the pulses from the sensor & calculates the vehicle’s RPM. LM35 is used as temperature sensor, the voltage o/p of the sensor is given to ADC, and the controller gets the reading from the ADC. An EEPROM is used to store the logs as well as the RPM & temperature set point. A RTC is used to keep the time so that the exact time of over speeding can also be logged.MAX232 is used to communicate with the PC.  

11.                       AQUARIUM AUTOMATION

Fishes are very sensitive to changes in temperature & surround lighting. In this project we maintain the temperature of the aquarium, the time at which the lights should be turned ON/OFF & the duration of oxygen motor. For this three relays are required one each for heater (temperature control), light & the Oxygen Motor. LM 35 is used as the temperature sensor for sensing the waters temperature, ADC 0808 is used to convert the LM 35’s output into digital value for the controller. RTC (Real Time Clock) is used for real time according to which the Bulb & the Oxygen motor is turned ON/OFF. A LCD is used to display the temperature as well as the time for turning ON & OFF the lights & the blower motor. The timing can be changed using a keypad & is then stored in the ROM area of the RTC. A battery backup is provided so even in case of power failure the real time is not corrupted.

12.                       Automated Pet Feeder

As pet lovers, we understand that the responsibilities of life sometimes inhibit pet owners from properly caring for their pets. Pet care should be fun, not burdensome, and so our goal with this project was to assist owners with pet care by providing a system that automates diet management.

A controller is used to activate a mechanical assembly using which a fixed amount of food is dispensed from the feeder unit after a specific duration the amount of food being dispensed as well as the time after which the food has to be dispensed can be entered using a keypad. A memory is used to save this setting.

13.                       INTELLIGENT STREET LIGHTING SYSTEM

Energy conservation reduces the energy consumption and energy demand per capita, and thus offsets the growth in energy supply needed to keep up with population growth. This reduces the rise in energy costs, and can reduce the need for new power plants, and energy imports. The reduced energy demand can provide more flexibility in choosing the most preferred methods of energy production.

In any city “STREET LIGHT” is one of the major power consuming factors. Most of the time we see street lights are ON even after sunrise thus wasting lot of energy. Over here we are avoiding the problem by having an automatic system which turns ON & OFF the street lights at given time or when the ambient light falls below a specific intensity. All streetlights are connected to a central computer from where the time at which the lights are to be turned ON/OFF can be set. An LDR is used to check if the lights have turned ON or not. This status is then sent to the central computer. Thus even the blown out lights can be detected. Each controller has an LDR which is used to detect the ambient light. We can operate the system in two modes the MANUAL MODE & AUTO MODE. In MANUAL MODE the lights are TURNED ON/OFF from the central computer. In AUTO mode if the ambient light is below a specific value the lights are turned ON.

14.                       BUS STOP AUTOMATION(using RFID)

In any city busses are one of the most common modes of public transport. When we arrive at a bus stop we are not sure if the bus that we want to board has gone or not. We don’t even know how much time it will take for the bus to arrive. Over here we try to solve this problem to provide better service to the commuter.

Each bus contains a RFID tag which contains the bus number. And each bus stop contains a RFID reader which reads this TAG.  All the bus stops are connected to each other & when a bus is detected at a stop the bus number is then sent to the next bus stop. The next bus stop receives the bus number & displays it ON the LCD along with the time at which the bus has arrived at the previous bus stop. Display is cleared only when the bus arrives at this stop & then the bus number is then sent to the Next Bus Stop.

Each bus stop consist of RFID reader whose data is sent to the Micro-Controller (8951/8952), which then sends the data to the next bus stop using 485 protocol & a LCD displays the Bus number & the time at which the bus has arrived at previous bus stop.
