microcontroller based lpg gas leakage system ppt

Ideal gas sensor is used to detect the presence of a dangerous LPG leak in your 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 LPG concentration. The sensor has excellent sensitivity combined with a quick response time. The sensor can also sense iso-butane, propane, LNG and cigarette smoke.

If the LPG sensor senses any gas leakage from storage the output of this sensor goes low. ....etc

lpg gas leakage detection alarm full report

In this article we will be discussing about a home security alarm circuit. This is a LPG gas leakage sensor circuit that detects the outflow of LPG gas and alerts the user via audio and visual indications. The heart of this simple engineering project is a gas sensor module SEN 1327. QM 6 gas sensor is used in this SEN 1327 module. The output signal from this gas sensor module is used to drive a 555 timer astable multivibrator. Here 555 timer works as a tone generator, the frequency of tone can be alt ....etc

The objective of this project is to detect any leakage of
LPG/CNG based cars, small scale factories or in home
appliances also. It will detect the leakage and will close the
knob of the system to stop the supply of the gas. Stepper
motor is there that could be attached with the knob and will
close the supply by rotating it. For assistance and LCD of
16x2 is also there. An alarm is there also the stop the alert the
user as soon as leakage is found.
Gas sensors are employed in a wide range of applications in
the fields of safety, health, ....etc
