hello guys,
i am working with MQ-7 and MG-811 sensors for arduino, i have searched several sensors looking for the circuits or some tips but could't find what i actually needed.
i was told that the calibration process including signal conditioning is the toughest part in these 2 sensors, and since i can't buy the sensors with signal conditioning because it's a uni project i have to implement it in the circuit.
If anyone has an idea on how to calibrate/signal condition the MQ-7 and MG-811 sensors please share your information with me.
Thank you.
