Where can I buy MQ-2 Smoke and Flammable Gas Sensor Module in Egypt?
MQ-2 Smoke and Flammable Gas Sensor Module is available from Makers Electronics and ElectroHub. Compare the offers above to find the best price.
How do I read this sensor with an Arduino?
Connect VCC to 5V, GND to GND and the analog output (AO) to an analog input such as A0. Allow the sensor to warm up before taking readings, since the values drift during the first minutes after power-up.
Can it measure an exact gas concentration?
No. MQ-2 responds to a range of gases and is best used to detect the presence or a rising level of gas. Precise concentration measurement needs a calibrated sensor and a reference setup.
