MQ-6 LPG and Iso-Butane Gas Detection Sensor Module (MQ6)

The MQ-6 LPG and Iso-Butane Gas Leakage Detector Sensor Module is a high-sensitivity electrochemical safety device engineered to safeguard environments against explosive gas build-ups. Driven by a rugged SnO2 (Tin Dioxide) semiconductor layer, this sensor boasts exceptional sensitivity to LPG, Iso-Butane, and Propane, with minimal cross-sensitivity to alcohol fumes or cooking smoke. The onboard carrier breakout board incorporates a versatile dual-signal layout: a 0-5V Analog Output (AO) for real-time concentration tracking and logging, and a TTL Digital Output (DO) driven by an onboard LM393 voltage comparator with an adjustable threshold potentiometer for immediate safety relay or buzzer triggers. Operating on a standard 5V power supply, it is the definitive hardware pick for smart kitchen safety arrays, automated gas cylinder monitoring nodes, industrial gas storage facilities, and DIY fire prevention projects using Arduino, ESP32, or Raspberry Pi.
