Air Quality Sensing With Ultra96V2 -

To create the application we need to be able to communicate with the air quality two senor using I2C. The sensor is different to I2C sensors that we have used in the past, the sensor we are using outputs nine bytes of information each a read is performed over the I2C bus. As such there is no I2C register map which we need to write to first before we perform a read command. In this instance we will be issuing …
