How do I connect it to an Arduino?
Connect VCC to 5 V and GND to GND. Read AOUT on an analog pin to get a value that changes with smoke intensity. Read DOUT on a digital pin, which goes HIGH or LOW when the level set by the potentiometer is crossed.
Can I connect it to a 3.3 V board such as ESP32?
The module is designed for 5 V supply, and its outputs may be higher than 3.3 V. Use a voltage divider or level shifter before feeding AOUT or DOUT into a 3.3 V board. Also allow a warm-up period after power-up before relying on readings.
