Introduction
The Gravity MQ9 sensor provides reliable detection of carbon monoxide and combustible gases through advanced thermal cycling technology - essential for home safety and industrial monitoring.
Dual-Temperature Detection
Precisely measures CO at low temperature (1.5V) and combustible gases (methane/propane) at high temperature (5V) through controlled thermal cycling.
Wide Detection Range
Accurately detects 10-1000ppm CO and 100-10000ppm combustible gases - covering both safety thresholds and industrial concentration levels.
Gravity Plug-and-Play
Standard 3-pin connector eliminates complex wiring - directly compatible with Arduino and other microcontrollers via analog input.
Adjustable Sensitivity
Built-in potentiometer allows fine-tuning for specific environmental conditions and detection priorities.
To ease the difficulty of using this sensor, a Gravity Interface is adapted to allow plug&play. The Arduino IO expansion shield is the best match for this senor connecting to your Arduino microcontroller.
