I got O3 sensor: Gravity: I2C Ozone Sensor (0-10ppm) from dfrobot
while I am integrating this sensor with raspberry pi and run the code available at your GitHub
the sensor showed "error 121"
I checked the I2c on raspberry pi and it connected
any solutions or guides for this problem

Hi
Please notice that Gravity: Electrochemical Ozone Sensor (0-10 ppm, I2C)(SKU:SEN0321) only support Raspberry Pi3, we didn't test it on other board yet.
Also, could you check the swithes on the sensor? Make sure that you enter the right I2c Address.
