ESP32 I2C read issue

[Manish Jugran]

Hi ,
I am using ADC121C_MQ4_Methane_Gas_Sensor with esp32 but not able to detect I2C address.What would be the I2C scan code for esp32 ?

The sensor, if it is I2C compatible should have a singular or range of addresses that can be used to read and write to it. If you cannot find this in a manual then search for 'I2C Scanner" this program will register all of the I2C nodes connected.
