but I am getting adc value very perfectly means red_data and ox_data but coming to here separate parameters like no2,nh3,co and c2h50h it is showing only 0.00ppm in serial monitor , iam using mics-4514 I2C sensor module with Arduino uno controller with 5v of power supply, can you please resolve this problem what is wrong here

I am using the sensor MICS-4514, which gives the same code without any changes. I checked connections and addresses by the I2C scanner, but the sensor still shows 0.00ppm for every parameter like C2H50H, NH3, NO2, and CO. What do I have to do now? Can you please help me with this problem?
