Dimensions 90mm AC LPG Leak Detectore, Model CI-2200, Name of Gases Detected LPG

Here is an ultra, Sensitive lpg sensor that generates loud beeps when it senses any gas leakage. It detects vapours of liquefied petroleum gas anywhere between 200 and 10, 000 ppm and drives a piezobuzzer to catch attention for immediate action. The buzzer beeps until the concentration of gas in the air decreases to a safe level. The circuit uses an mq6 gas sensor, Crafted for to propane and, Sense lpg isobutane gases. Lpg gas is supplied in pressurised steel cylinders. As this gas is heavier than air, When it leaks from a cylinder it flows along floor and tends to settle in low spots such as a basement. This can cause fire or suffocation if not dealt with. Here is a circuit that detects the leakage of lpg gas and alerts the user through audio, Visual indications. Fig. 1 shows the circuit of the gas leakage alarm. As per its datasheet, It has high sensitivity to propane, Butane, Isobutene, Lpg and natural gas. The sensor is additionally capable of being employed for identification combustible gases, Especially methane. This circuit has been tested with lpg gas and was found to work satisfactorily. Whenever there is lpg concentration of 1000 ppm parts per million in the area, The out pin of the sensor module goes high. This signal drives ic2, Hex invertin bufferr. Current, Limiting resistors r5 and r4, Respectively. Led d1 glows and the alarm sounds to alert the user of gas leakage.
