20210505· And for some reasons, the button ceases to make a difference after 23 changes of mode. I sincerely need help here. “Ro = MQCalibration(MQ_PIN);”: This statement needs to be run to calibrate the sensor. Is there any way to reflect that on the Display? A statement like “Calibrating” would be better since with the present code, the deplay remains blank for the duration of calibration ...
It''s obvious that different sensor can detect the same gas. Such as MQ2, MQ3, MQ5, Alcohol Sensor, Grove – HCHO Sensor can detect Alcohol. So if you want an alcohol sensor, then which on should you chosen? Although most of the above sensors are able to detect Alcohol, but you should know that they have different range to Alcohol.
