2021-01-09· After turn on the power supply MQ2 gas sensor start sensing LPG gas is present in the air or not. If LPG gas leaks from a cylinder then the MQ2 gas sensor detects it and provides LOW (Ground/0v) output voltage from the “D0” pin. This output voltage goes to the Base terminal of the BC557 Transistor and the transistor becomes active.
2020-02-12· Here we have designed Arduino based LPG gas detector alarm that will detect the leakage and creates an alert. About Project. LPG Gas Sensor Module. This module consists of an MQ3 sensor that actually recognizes LPG gas, a comparator (LM393) for comparing MQ3 output voltage with a reference voltage. When LPG gas is detected it will give high output.
Here is a gas leak detector circuit that detects the leakage of LPG gas and alerts the user through audio-visual indications. The circuit operates off a 9V PP3 battery. Zener diode ZD1 is used to convert 9V into 5V DC to drive the gas sensor module. The gas leakage circuit uses the SEN-1327 gas sensor module from RhydoLABZ.
2. MQ6 Sensor They are used in gas leakage detecting equipment in family and industry, are suitable for detecting of LPG, iso-butane, propane, LNG, avoid the noise of alcohol and cooking fumes and cigarette smoke. Figure3: MQ6 SENSOR Structure and configuration of MQ-6 gas sensor is (Configuration A or B), sensor composed by micro AL2O3
