mq 9 module Carbon Monoxide (CO) and flammable gas sensor

Description:

Overview 

This Carbon Monoxide (CO) and flammable gas sensor detects the concentrations of CO and combustible gas in the air and outputs its reading as an analog voltage. The sensor can measure concentrations of CO from 10 to 10,000 ppm and flammable gas from 100 to 10,000 ppm.The sensor can operate at temperatures from -10 to 50°C and consumes less than 150 mA at 5 V. Please read the MQ9 datasheet for more information about the sensor.
 
This module provides both digital and analog outputs. Threshold level for digital output can be easily adjusted using the preset on the board. MQ-9 sensor module can be easily interfaced with Microcontrollers, arduino and etc.
