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

lpg gas leakage detector 8051 microcontroller ppt download

Abstract

The presence of dangerous LPG leakage in the cars, service station or in the storage tank environment can be detected using the Ideal Gas Sensor. This LPG gas leakage detector unit can be easily integrated into a unit that can sound an alarm or give a visual suggestion of the LPG concentration. The sensor has both admirable sensitivity and rapid response time. This sensor can also be used to sense other gases like iso-butane, propane, LNG and even cigarette smoke.The output o ....etc
