I’m trying to use mics 2714 to create an air quality measurement circuit.
The problem is not the circuit itself (power, connections, etc) but its non-linearity!
The datasheet has got only a graphic about Rs/R0 ratio in relation to NO2 concentration but I need a formula to be implemented into microcontroller.
Thereover, does this sensor need any temperature or humidity compensation?
The goal is to measure the absolut value of NO2 concentration.
Can anyone help me?
Thanks (and sorry for my English )
