  * @brief Reading ozone concentration, A concentration of one part per billion (PPB).
  * @n step: we must first determine the iic device address, will dial the code switch A0, A1 (ADDRESS_0 for [0 0]), (ADDRESS_1 for [1 0]), (ADDRESS_2 for [0 1]), (ADDRESS_3 for [1 1]).
  * @n       Then configure the mode of active and passive acquisition, Finally, ozone data can be read.
  * @n note: it takes time to stable oxygen concentration, about 3 minutes.
  *
  * @n The experimental phenomenon is to print one billionth of the ozone concentration on the serial port.
  * @n Because the value measured by the sensor is less than 10000, the value obtained will not be greater than 10000
