MQ 9 is a Semiconductor Sensor for CO/Combustible Gas. For proper operation, it needs to supply 1.5V for 90s and then 5V for 60s according to the datasheet. However, my question is How can I do this. I have a MUC (8051), a step-up circuit with the chip ME2108 to generate 5V. What else do I need to build the circuit performing such function.
Please Help!!

But I don't understand the method the website showed, it is very complicated.
Can someone help me, please
