Multiple Sensors in One Arduino Uno R3

Good day!

Noob here, needed help quickly! I am planning to use multiple formaldehyde sensors in my Arduino Uno, however, can I use 12 sensors in just one Arduino Uno R3, then how to read its measurements? also the sensor needs base shield v2.

Kindly help me since I will use this for my thesis.

Regards, krpagdanganan.

Don't you think telling us the type of sensor you are asking about is a pretty important detail? Are there other details you're leaving out? Remember, none of us have been there working on this with you.

More and more I believe, common sense is becoming a superpower these days.
