Abstract:
This Gas Sensor (MQ6), ideal sensor for use to detect the presence of a dangerous
gas leak in your Home, car or in a service station, storage tank environment. This unit can be
easily incorporated into an alarm unit, to sound an alarm or give a visual indication of the
Combustible Gas / LPG concentration. The sensor has excellent sensitivity combined with a
quick repsonse time. The sensor can also sense iso-butane, propane, LNG and cigarette smoke.
This project is High Sensitivity to LPG, iso-butane, propane. This also can sense to
alcohol and smoke, but with poor sensitivity. This project is designed to detect the LPG from
100parts per million (PPM) to 10,000 PPM. Whenever LPG is detected, the sensor produces the
output voltage, which is depended on the amount of gas leakage. This voltage drives the
transistor into saturation region. A buzzer is connected to produce audible alert signal.
In this project we use different modules such as Zigbee (Tx, Rx), LPC2148 as controller, Gas
Sensor (MQ-6), Buzzer to detect the presence of gas and display wirelessly on PC.
ZigBee is the name of a specification for a suite of high level communication
protocols using small, low-power digital radios based on the IEEE 802.15.4 standard for wireless
personal area networks (WPANs), such as wireless headphones connecting with cell phones via
short range radio. The technology is intended to be simpler and cheaper than other WPANs, such
as Bluetooth. ZigBee is targeted at radio-frequency (RF) applications that require a low data rate,
long battery life, and secure networking ZigBee is a low-cost, low-power, wireless mesh
networking standard. The low cost allows the technology to be
widely deployed in wireless
control and monitoring applications, the low power-usage allows longer life with smaller
batteries, and the mesh networking provides high reliability and larger range

This Gas Sensor can be used to make wireless Gas leak detector in home security system
ARM29
The LPC2148 are based on a 16/32 bit ARM7TDMI-S™ CPU with real-time
emulation and embedded trace support, together with 128/512 kilobytes of embedded high speed
flash memory. A 128-bit wide memory interface and unique accelerator architecture enable 32bit code execution at maximum clock rate. For critical code size applications, the alternative 16bit Thumb Mode reduces code by more than 30% with minimal performance penalty. With their
compact 64 pin package, low power consumption, various 32-bit timers, 4- channel 10-bit ADC,
USB PORT,PWM channels and 46 GPIO lines with up to 9 external interrupt pins these
microcontrollers are particularly suitable for industrial control, medical systems, access control
and point-of-sale. With a wide range of serial communications interfaces, they are also very well
many other general-purpose applications.
This project uses two power supplies, one is regulated 5V for modules and other one is
3.3V for LPC2148. 7805 three terminal voltage regulator is used for voltage regulation. Bridge
type full wave rectifier is used to rectify the ac out put of secondary of 230/12V step down
transformer.
