arduino uno - Pre-heat time required for MQ-5 gas sensor ...

Only if you want a very accurate measure of gas concentration, you will need to wait those 24h (and also have a good calibration of your sensor, as well as means to compensate other environmental factors like temperature, humidity, etc.). But if you wanted to do this kind of measurement you probably won't be using a MQ-5 sensor anyway. EDIT:
