LPG Gas Leakage Sensor Alarm Circuit | Electronic ...

LPG Gas Leakage Sensor Alarm Circuit This circuit has been tested with LPG gas and was observed to do the job satisfactorily. Whenever there's LPG concentration of 1000 ppm (parts per million) in the spot, the OUT pin of the sensor module goes higher. This signal drives timer IC 555, that is wired as an astable multivibrator. The multivibrator generally works as a tone generator.

10 Signs Of A Carbon Monoxide Leak | Alarm Inc.

Carbon Monoxide (CO) is gas you cannot see or smell which is produced by the incomplete processing of solid, liquid, and gaseous fuels, as well as appliances fuelled with oil, liquefied petroleum (LP gas), natural gas, coal, kerosene, or wood. Burning charcoal or running a non-electric machine (car or lawn mower) produces CO gas. Normally, the small amounts of CO released by heating equipment ...
