I need help working on a digital airflow sensor with the following link
As far as i know, the address of this sensor is 49, but i received a comment saying that for the "read" bit i need to send 93rd instead. May i know how to deal with this?
I think you're looking for a general purpose I2C tutorial. Since there can be multiple devices on an I2C bus each device needs its own address ("49"); the "93" is just the byte you send to it to get it to send data back.
