1. Introduction The MH Series “Flying Fish” (also known as MH-Z or simply MH breakout boards) are a family of compact, easy-to-use sensor modules designed primarily for gas detection using MQ-series gas sensors (e.g., MQ-2, MQ-3, MQ-5, MQ-7, MQ-9, MQ-135, etc.). The “Flying Fish” nickname refers to the board’s distinctive shape and the 3-pin “Fish” connector (GND, VCC, OUT) commonly used in hobbyist and educational kits. void loop() Gas alarm: ")
