Sell MQ-2 Smoke Gas LPG Hydrogen Sensor Detector Module For Arduino best price

The MQ-2 Gas sensor can detect or measure gasses like LPG, Alcohol, Propane, Hydrogen, CO and even methane. The module version of this sensor comes with a Digital Pin which makes this sensor to operate even without a microcontroller and that comes in handy when you are only trying to detect one particular gas. Pin Configuration: 1 Vcc - This pin powers the module, typically the operating voltage is +5V 2 Ground - Used to connect the module to system ground 3 Digital Out - You can also use this sensor to get digital output from this pin, by setting a threshold value using the potentiometer 4 Analog Out - This pin outputs 0-5V analog voltage based on the intensity of the gas Features: Operating Voltage is +5V Can be used to Measure or detect LPG, Alcohol, Propane, Hydrogen, CO and even methane Analog output voltage: 0V to 5V Digital Output Voltage: 0V or 5V (TTL Logic) Preheat duration 20 seconds Can be used as a Digital or analog sensor The Sensitivity of Digital pin can be varied using the potentiometer Alternative MQ Gas sensors: Sensor Name Gas to measure MQ-2 Methane, Butane, LPG, Smoke
