Each MQ sensor is "tuned" for specific gases. Common versions found in the Flying Fish lineup include: MQ-2 Semiconductor Sensor for Combustible Gas - Pololu mh mq sensor flying fish

MQ sensors (MQ‑2, MQ‑3, MQ‑135) can effectively detect a moving gas source (“flying fish”) when used in a small array with a transient‑sensitive algorithm. Key points: Key points: : Usually VCC (5V), GND, Digital
: Usually VCC (5V), GND, Digital Output (D0), and Analog Output (A0).
A single MQ sensor gives only concentration, not direction. To track a moving source, use an of 3–4 sensors.
While "Flying Fish" is the module brand, the designation refers to the specific gas-sensing element. These sensors operate on a semiconductor principle: a small internal heater warms a sensing layer (often Tin Dioxide, SnO2cap S n cap O sub 2
