The Grove - Gas Sensor(MQ9) module is useful for gas leakage detecting (in home and industry).

  • Overview
  • It can detect combustible Carbon Monoxide, Coal Gas and Liquefied Gas. The sensitivity can be adjusted by the potentiometer.

    Hardware Overview

    This is an Analog output sensor. It needs to be connected to any one Analog socket in Grove Base Shield. It is possible to connect the Grove module to Arduino directly by using jumper wires. When doing so, please refer to the connection table below:

    The output voltage from the Gas sensor increases when the concentration of gas. Sensitivity can be adjusted by rotating the potentiometer. Please note that the best preheat time for the sensor is 24 hours and above.

    Note: Hot-swapping the grove may lead to IC burnout, please turn off the power of main board before swapping grove.
