), which changes its electrical resistance when it encounters specific gas molecules. The Flying Fish module typically features:

The label refers to a popular series of sensor breakout boards manufactured by MH Electronic . These modules, identifiable by their distinct blue PCBs and "Flying Fish" branding, are designed to make high-performance sensors—like the MQ gas series —accessible for rapid prototyping with microcontrollers like Arduino, ESP32, and Raspberry Pi. Understanding the MH MQ "Flying Fish" Series

Standard MQ calibration uses clean air baseline (Rs/R0 ratio). For moving sources:

The flying fish passed closest to S1 at t≈120 ms.

Flying fish have evolved to develop a distinctive body shape, with a streamlined torso, large pectoral fins, and a small caudal fin. As they glide through the air, they use their pectoral fins to generate lift, while their caudal fin provides stability and control. By studying the flying fish's movement patterns and body shape, researchers can gain insights into its remarkable aerodynamic performance.
