How do I wire the MQ-8 to an Arduino?
Connect VCC to 5V, GND to GND, AO to an analog input for a measured level, and optionally DO to a digital input for a threshold alarm.
Can I connect the MQ-8 directly to a 3.3 V board like ESP32?
The module runs on 5 V. Its analog output can rise above 3.3 V, so use a voltage divider or level shifter on AO before connecting it to a 3.3 V board.
