Hi,
it's my first post here, so pls don't mind if something isn't 100% correct. I am quite experienced in sensor electronics, did programming for sensor data acquisition on PC / Windows some years ago, know analogue and digital electronics quite well. Only the Arduino is new to me.
I wanted to make a CO gas detection. And there are plenty of projects exactly doing this. And plenty of discussions that sensor readouts vary...
But when I see the data sheet of the MQ7 sensor it tells me that the readouts vary with humidity and temperature. But none of these projects do have a temperature and humidity sensor attached...
Or did someone build that already? At least there is a DHT11 named sensor (humidity and temp) available.
