arduino uno Preheat time required for MQ5 gas sensor ...

When the manufacturer writes in the datasheet that the preheat time is 24 hours, then you should do 24 hours. I suggest to connect the sensor in a normal way, with ''A'' en ''B'' pins connected and with the load resistor, and keep it on for 24 hours. Maybe it is already stable after a few hours, but keep it on for 24 hours to be sure. To take a measurement, the sensor needs time to warm up. About ...
