Gas leakage detector mini project pdf


gas leakage detector mini project pdf

The gas leakage circuit uses the.
Interfacing with the sensor supernatural season 1 episode 1 direct module is done through a 4-pin SIP header.
Zener diode ZD1 is used to convert 9V into 5V DC to drive the gas sensor module.
Gas leak detector schematic, sEN1327 gas sensor pin details and picture.
Here is a gas leak detector circuit that detects the leakage of LPG gas and alerts the user through audio-visual indications.Its output goes high when the gas level reaches or exceeds certain point.The multivibrator basically works as a tone generator.The circuit operates off a 9V PP3 battery.An MQ-6 gas sensor is used in the gas sensor module.Use a suitable heat-sink for transistor SL100.



The sensor can also be used to detect combustible gases, especially methane.
This signal drives timer IC 555, which is wired as an astable multivibrator.
The pitch of the tone can be changed by varying preset VR1.
A preset in the module is used to set the threshold.
Output pin 3 of IC 555 is connected to LED1 and speaker-driver transistor SL100 through current-limiting resistors R5 and R4, respectively.Whenever there is LPG concentration of 1000 ppm (parts per million) in the area, the OUT pin of the sensor module goes high.LED1 glows and the alarm sounds to alert the user of gas leakage.Pin details of the gas sensor module are shown in Fig.SEN-1327 gas sensor module from Rhydolabz.Pdf Text File (.txt) or read online.Mini project pDF ).Advanced, gAS, detect AND alert system.Gas, sensor can be used to make wireless.Gas leak detector in home security.
