What is the code and library for this instead
Hi, would you please elaborate a little bit more? What are you trying to do?

SCD30 airSensor;
void setup() {
Serial.begin(9600);
Serial.println(“SCD30 Example”);
Wire.begin();
if (airSensor.begin() == false) {
Serial.println(“Air sensor not detected. Please check wiring.”);
while (1); // Halt if sensor not found
}
// Optional settings (adjust as needed)
airSensor.setMeasurementInterval(2); // Set measurement interval in seconds (2-1800)
airSensor.setAltitudeCompensation(0); // Set altitude compensation in meters
airSensor.setAutoSelfCalibration(true); // Enable auto-self-calibration
}
void loop() {
if (airSensor.dataAvailable()) {
Serial.print("CO2(ppm): ");
Serial.print(airSensor.getCO2());
Serial.print(" Temperature(C): ");
Serial.print(airSensor.getTemperature(), 1);
Serial.print(" Humidity(%): ");
Serial.print(airSensor.getHumidity(), 1);
Serial.println();
}
delay(1000); // Wait 1 second between readings
}
Is this code correct based on the sensor reading ? Help me rectify it and what is the library needed as when i tried it , no results shown .
What kind of air does this code measure
air quality for CO2
same thing happened to me even after downloading the 3 libraries and using the examples from hookup guide
Check your serial baud rate in arduino, it must match the baud rate in the code.
Like Yellowdog said, try 115200 baud
