Vehicle Accident Prevention System with Eye Blink Sensor

Automobile has great importance in our daily life. We utilize it to go to our workplace, travel all over the place, deliver goods. Speed is one of the important to consider while driving and the driver stress of the over-shift it also leads to the sudden accident. The Speed of the vehicle can be measured with help of speed limiter so the speed is controlled and also if the driver is tired or not can be checked.

The IR Sensor is used to detect the eye blinking. The eye blink is a sensor which is placed in front of the driver on the top. While in driving time the eye blink in normal means it checks when the eye close to particular second’s buzzer will be indicated to alert him to wake up.

The microcontroller plays the important role to control the whole operation in these concepts, the sensor feed the signal to the controller then the only buzzer is indicated.

Project Description:

1. AT89S52: The AT89S52 is a low power, high performance CMOS 8-bit microcontroller with 8k bytes of in-system programmable flash memory. This is a powerful microcontroller which provides high flexibility and cost-effective solution to many embedded control applications. It has the following standard features: 8K bytes of flash, 256 bytes of RAM, 32 I/O lines, watchdog timer, 2 data pointers, 3 16-bit timers/counters, on-chip oscillator and clock circuitry.
2. Infrared sensor: An infrared sensor is an electronic instrument which is used to sense certain characteristics of its surroundings by either emitting and/or detecting infrared radiation. Infrared sensors are also capable of measuring the heat being emitted by an object and detecting motion.

The wavelength region which ranges from 0.75 to 3µm is known as the near-infrared regions. The region between 3 and 6µm is known as the mid-infrared and infrared radiation which has a wavelength greater higher than 6µm is known as far infrared. Infrared technology finds applications in many everyday products.

3. Buzzer: A beeper is an audio signaling device, which may be mechanical, electromechanical, or piezoelectric. Mostly used to alarm devices, timers, etc. Its power supply is 5v DC source its sound like heavy its ON.

Project Implementation:

1. You need the microcontroller to be programmed as if the sensor valve to the input of the controller checks everytime.
2. Connect the terminal of IR Sensor as 5v,GND, Signal PIn to the controller.
3. Check sensor with the eye contact and the beeper will on if eye is closed to perticular seconds.

Software requirements:

1. Keil Uvision 3: Keil Software makes C compilers, macro assemblers, real-time kernels, debuggers, simulators, integrated environments and evaluation boards for the 8051, 251, ARM and XC16x/C16x/ST10 microcontroller families
2. Programming language: Embedded C language
