About this item
- The MQ-2 sensor responds to LPG, methane and smoke.
- The Arduino warms it up, learns the clean-air reading and sounds the buzzer when the gas level climbs past a threshold, showing the level on a 16 × 2 LCD.
- A practical project for kitchens and labs, and a lesson in calibrating analog sensors.
- The complete kit is the whole parts list as a single item: we collect every part, check it and ship the set together, so nothing is missing when you sit down to build.
- Prefer to buy only some of the parts?
- The project page lists every part with its own price, and you can add just the ones you need.
