This project saves Human lives from an accident by detecting an accident before it occurs or in case it happens. But this need advance accurate human detection and also accident detection capability. This project includes features like Vibration detection, Eye blink rate detection, alcohol detection, Vibrating unit for alert and location of vehicle track using GSM and GPS technology.
This system consists of two parts, alerting part and messaging part. The Vibrating alert to driver is delivered by a vibrator motor placed at hands and also displayed on LCD placed in front it. It also reports the current details of the monitor parameters with the current location of vehicle to the authorized phone number in the form of SMS through a GSM and GPS modem at any abnormal event as well on demand by authorized phone. The project hardware design consists, a MQ3 Gas sensor which continuous sense if any alcohol is detected in side vehicle, An Eye blink detector is placed in front of driver’s eye which continuous monitor the rate of eye flip of driver for sleepy condition. A Vibrator sensor is used to sense the abnormal vibration occurs inside a vehicle at any accident situation. An advanced Microcontroller of AVR Series continuously scan the all these sensors parameters and It enables intelligent prevention and detection of any accident situation, it alert and reports in real time on such abnormal condition of accident for the precautionary measure and emergency help to avoiding the any severity situation due to accident. The place of the vehicle is identified using Global Positioning system (GPS) and Global system mobile communication (GSM). These systems constantly watch a moving Vehicle and report the status on demand by the authorized mobile. The system is powered through +5 and +12 Volt dc regulated power supply, which can also be powered through a battery of vehicle itself. To show vehicle operating here we use a dc motor which is operated in normal condition through a motor driver circuit interfaced to the controller, while at any abnormal condition caused and ensed by preventing sensors it becomes stopped.
This project is aimed to develop an advanced hi-tech wireless notice board. Unlike the sticking various notices day to day manually it’s quite a difficult and which also engage a person to look after it, the proposed wireless GSM based mobile operate notice board is the quite convenient to communicate the notice from any remote place, which is also highly demanded in now adays in frequent uses at the various places such as in institutes, public places like bus stations, railway stations and parks.
The main objective of the project is to develop a wireless notice board that displays notices when a message is sent from the users mobile. While the user sends the message from the mobile, it is received and retrieved by the GSM modem at the display unit. The desired number is auto saved on the microcontroller over a missed call. It is then sent to the microcontroller that further displays the notice sent from the user on to the electronic notice board which is equipped with a 20X4 LCD display.
The project design involves an advance microcontroller interfaced to a GSMmodule and +5V/12V regulated supply. The power supply consists of a step-down transformer 230/12V, which steps down the voltage to 12V AC. This is converted to DC using a Bridge rectifier. The ripples are removed using a capacitive filter and it is then regulated to +12V for GSM module supply and +5V for the operation of the microcontroller and display.
This system can be further enhanced by making the audio announcement of notices by interfacing a text to voice conversion device.
There is a growing group of various wireless devices targeted at residential and commercial energy consumers that monitor, control, and automate the delivery and use of energy. The proposed system for home-office automation of Smart Energy (SE) compliant devices is that they can form a global wireless GSM network regardless of the product/appliances manufacturers. This system is very useful for multiplex, multi stories buildings and big houses / offices.
This project aim to make automation of appliances with wireless power metering. To create a breaker-level power metering over wireless device that would sit next to the home's main distribution panel (or subpanel) and measure the power on up to 4 different circuit lines and output the energy data over wireless GSM network to any remote GSM Phone. The current is measured in a non-contact manner so that any user could safely install the current sensors.
At the user side, the Load current and voltage values from the power supply is obtained at the current and voltage transformer respectively. The current and voltage values are sent to the ADC of microcontroller which converts analog to digital values. The power is calculated in the microcontroller with the obtained current and voltage values. The value of power calculated in microcontroller is displayed in the LCD display. Then the controller sends the information to the remote side by using wireless GSM module. If the power consumed exceeds the fixed power value set up by the user and if the power to one or two phase is cut off, a relay is given by the relay driver circuit and so the power supply is not given to the load. This is indicated by the corresponding message in the LCD display and then tripped. At any time user can switch ON/OFF the connected electrical Appliances remotely just by sending predefined SMS text command over wireless GSM network.
If the user did not pay the bill after the due date, tripping information is sent to the user side which is shown in the LCD display. It suspect that the concept of this wireless Automation with SE-Power Meter would be extremely useful for landlords and small businesses looking for a low cost way of automation with monitoring multiple buildings or renting out portions of the same home. This system makes it easy and cheap for the commercial building owner to monitor the energy usage.
This project is based on Global Positioning System (GPS) and a programmable microcontroller to measure the distance between two points. The main aim is to develop such a compact and less expensive device, which can be more useful for the patrolling/inspection or any other application where large distance measurement is often required.
The project is designed using an advance microcontroller ATmega328 interfaced to a GPS device. Also provided an external micro SD RAM for data storage and 9 volt Lithium-ion battery for standalone power supply to device. The GPS receiver receive the transmit radio signals from GPS satellites and calculate its geographical position in terms of four dimensions x, y, z (latitude, longitude and elevation) and time. These data are transferred to microcontroller in the standard protocol and data frame (ASCII code packet) by serial UART communication. To start distance measurement press a switch ( connected to device) from an initial point and move to a desired location along with this assembly, unpress a switch reaching to the end point. The distance measurement values will flash continuous on LCD display and at the same time all readings including serial no., date, time, latitude, longitude and distance (instantaneous (d) and total (D) ) will be dumped into a text file, which will be stored automatically on the micro SD memory card attached to the device.
This project can be further enhanced by interfacing a GSM System for sending the measurement data to any remote mobile as well can view the location on Google map on remote PC or laptop.
