Data Analysis

When the IR CO2 sensor get 5V power supply, it will output 0.4~2V analog value, corresponding to 0~5000 ppm And when the sensor finds faults during the self-checking process, it will output 0V.

Sample Code
* Infrared CO2 Sensor0-5000ppm * * This example The sensors detect CO2 * * * V1.0 * 2016-7-6 * * GNU Lesser General Public License. * See for details. * All above must be included in any redistribution *
int sensorIn = A0;
void Serial.begin 9600 // Set the default voltage of the reference voltage analogReference DEFAULT ;
void //Read voltage int sensorValue = analogRead sensorIn ;
// The analog signal is converted to a voltage float voltage = sensorValue* 5000/1024.0 if voltage == 0

Serial.println "Fault" else if voltage < 400

Serial.println "preheating" else
int voltage_diference=voltage-400 float // Print Voltage Serial.print "voltage:" Serial.print voltage Serial.println "mv" //Print CO2 concentration Serial.print concentration Serial.println "ppm" delay 100 ;

Expected Results

Open your IDE serial monitor and wait for 3 minutes preheat process , then you'll see the finial data. Indoor Temperature 30
