MQ2 Gas Sensor Pinout, Features, Equivalents & Datasheet

· Where to use MQ-2 Gas sensor: 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. When it comes to measuring the gas in ppm the analog pin has to be used, the analog pin also TTL driven and works on 5V and hence can …

How to Calibrate And Use MQ9 Gas Sensor w/ Arduino

1. Do not expose this sensor to water and frost. 2. Applying a voltage higher than 5V or applying the voltage to the wrong pins may damage the sensor. 3. Exposing the sensor to a high concentration of gases for a long time may have a negative effect on its performance. 4. Shaking or vibrating the sensor may decrease its accuracy.

Configure and read out the Raspberry Pi gas sensor (MQ-X)

If you use a sensor other than the MQ-2 and it has a different voltage, the setup must of course be adjusted. After the MCP3008 is correctly connected, we use port 0 and connect it to RX0 of the TTL. On the opposite side is RX1, which is connected to the analog pin (A0) of the MQ2 sensor. Also connect from the Raspberry Pi (LV) and 5V (HV) to the TTL. And also 5V to the VCC pin of the gas ...
