GAS LEAKAGE DETECTION & AUTO ON-OFF GAS SYSTEM
This system helps you to upgrade your safety standards, comply statutory requirements on environmental commitments and most important and basic function being prevent accidents and protect life and property from disaster. In the past, it has been a conventional practice to employ combustion apparatus such as a furnace,
heater, stove or LPG kit in cars, which utilizes a combustible vapor or gas to produce heat energy when properly ignited. In the u ....etc

smoke alcohol and lpg detection alarm seminar

This board can be used for measuring LPG leaks, which could be used in your home to identify gas leakage.This LPG Gas Sensor (MQ6) is used to detect dangerous LPG leak in your surrounding,home,car,storage tank and etc.This unit can be easily added to alarm unit to produce sound or visual indication of Gas/LPG.The sensor has excellent response time.It can used to sense iso-butane,LNG,Cigarette Smoke and propane.It can also be used for wireless gas leak detector project.

This project is designed to monitor the LPG leakage or smoke and activate the siren and auto dialer using ARM based microcontroller. LPG Sensor is used to sense the leakage. A buzzer is provided to alert the user in abnormal condition.
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 (kB) of embedded high speed flash memory. A 128-bit wide memory interface and a unique accelerator architecture enable 32-bit code execution at maximum cl ....etc
