Mh: Mq Sensor Flying Fish

const int numSensors = 3; float baseline[numSensors]; float current[numSensors]; float delta[numSensors];

Standard MQ calibration uses clean air baseline (Rs/R0 ratio). For moving sources: mh mq sensor flying fish

The combination of MH-MQ sensors and flying fish research demonstrates the power of interdisciplinary approaches, driving innovation and discovery at the intersection of biology, engineering, and environmental science. const int numSensors = 3; float baseline[numSensors]; float

void loop() for (int i=0; i<3; i++) float val = analogRead(mqPins[i]); float ratio = val / baseline[i]; if (ratio > 1.15) // 15% rise Serial.print("Flying fish near sensor "); Serial.println(i); delay(500); // debounce const int numSensors = 3

void loop() for (int i=0; i<numSensors; i++) current[i] = readSensor(i); delta[i] = (current[i] - baseline[i]) / baseline[i]; // relative change if (delta[i] > THRESHOLD && delta[i] < 0.8) // sharp rise // Flying fish detected near sensor i recordPeak(i, millis());
