Hello,
After analysing the datasheet of the MICS 2714, it appears that the MICS consists of a resistors that vary with the concentration of NO2 .
What can I do ?
-Show you how to connect the sensor to the arduino
- do a program that gets the concentration of NO2 in ppm and displays it on the serial monitor / or on a screen or a LED IHM
Feel free to contact me to have more informations .
