Mq131 ozone sensor measurement error

Hi there!

I recently bought Arduino Uno Compatible I2C Shield + MQ131 Ozone Gas Sensor. Despite the fact that I produce ozone gas from the generator, I can’t measure proper values at all. The sensor reads 1.9 ppm when there is no ozone produced and goes down dramatically when it is produced. I am using the arduino code in this repository. Furthermore, I get a compile error that goes;

< “no headers files” (.h) found in C:\Program Files (x86)\Arduino\libraries\ADC121C_MQ131_Master >

< collect2.exe: error: ld returned 1 exit status
exit status 1 >

I simply cannot run the program with this hardware. Could you recommend any other program that I can use? or Could you give me a solution on this problem?

Best Regards,
