VEHICLE GAS DETECTION WITH AUTOMATIC SAFETY WARNING SYSTEM USING GSM TECHNOLOGY
The more you drive your car, the more you are at risk.
Cars with over 100,000 miles on them are very dangerous.
white gas resembling water vapor blows out of the air vents in the car. This is the gas in its more concentrated form.
Causes Lung Cancer and Alzheimerâ„¢s disease
Affects included extreme drowsiness, memory loss, and not being able to concentrate on driving.
Need of good safety system
Avoid health risk
Project aims to modify an existing safety model employed in automotive field
Designing a microcontroller based toxic gas detection system
Offers faster response time
BASCOM BASIC 8051
The processor ,the RAM,ROM,I/O Ports and Timer are all embedded together on one chip
- 8K ROM
- 256 RAM
- 3 Timers
- 32 I/O Pins
- 1 serial port
- 8 Interrupt sources
PIN DESCRIPTIO N
Total 40 pins
Each port has 8 pins
Rest of the pins are Vcc,GND,XTAL1,XTAL2,RST,EA,PSEN and ALE
gas sensor used to detect various combustible gases
There is a sensing element inside the stainless steel mesh.
resistance of the sensing element reduces rapidly
There is a heating element inside the sensor.
The heater terminals should be connected to 5V DC.
The sensor can be wired using a general purpose op-amp such as 741 in comparator mode.
Also by using a variable resistor, the sensitivity can be adjusted very easily
Wide detecting scope
Fast response and High sensitivity
Stable and long life
Simple drive circuit
GSM â€œGlobal System for Mobile Communication
A GSM modem is a wireless modem that works with a GSM wireless network.
sends and receives data through radio waves.
Like a GSM mobile phone, a GSM modem requires a SIM card from a wireless carrier in order to operate.
GSM modems can be a quick and efficient way to get started with SMS.
GSM modems are a cost effective solution for receiving SMS messages.
MAX232 is a Voltage converter
Converts RS232 voltage levels to TTL voltage levels and viceversa
It uses +5V power source
Two sets of line drivers for transferring and receiving data
