Needs better docs
Works but the wiki link was broken. Had to find code elsewhere.
5 FAQ
Q: Can I use this as a primary home safety alarm?
A: No, this is for prototyping and educational purposes only. Use certified devices for safety.
Q: Is the potentiometer for sensitivity?
A: Yes, the blue potentiometer adjusts the digital output threshold.
Q: Does this work with 3.3V logic?
A: The sensor needs 5V, but DO can be adjusted. AO outputs 0-5V.
Q: How long until it reads accurately?
A: Please allow at least 5 minutes of warm-up time after powering on.
Q: What gas does this not detect?
A: It is specific to combustible gases like LPG. It does not detect CO or smoke primarily.
