Can you modify or guide that code about sending the data to Thingsspeak by maintaining the same functionality of the code? Ref- https://electrosome.com/iot-temperature-data-logger-esp8266-lm35/ but here the functionality of the temperature is different.Mine is CO2 Sensor

int analogPin = A3;
int Rawval ; // variable to store the value read
int Scaleval ;
int RELAY_pin = 10; // Relay is connected to pin D10
void setup()
{
Serial.begin(9600); // setup serial
pinMode(RELAY_pin, OUTPUT);
}

void loop()
{
int Rawval = analogRead(analogPin);
Serial.print("Rawvalue from Analog input =");
Serial.print(Rawval);
// For 3V3 input to read 100%, 3V3 of 5V ref = (3.3 / 5) * 1023 = 675
Scaleval = map(Rawval, 0, 675, 0, 20);
Serial.print(" Scaled Value =");
Serial.println(Scaleval);
