MQ - 2 is a flammable gas and smoke sensor detects the concentrations of combustible gas in the air and outputs its reading as an analog voltage.
• Operating Voltage: 4.5V to 5V DC.
• High sensitivity to smoke and flammable gasses
• Good sensitivity to Combustible gas in wide range
• Interface type: Analog
• Long life and low cost
MQ - 2 Smoke and Flammable Gas sensor
• They are used in gas detecting equipment for smoke and flammable gasses in family and industry or car.
• Portable Gas Detector.
The gasses detected by these gas sensors can be deadly in high concentrations. Always be careful to perform gas tests in well ventilated areas.
