Description:

This Carbon Monoxide (CO) and flammable gas sensor detects the concentrations of CO and combustible gas in the air and ouputs its reading as an analog voltage. The sensor can measure concentrations of CO from 10 to 1,000 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 (180k pdf) for more information about the sensor.

Connections:

Connecting five volts across the heating (H) pins keeps the sensor hot enough to function correctly. Connecting five volts at either the A or B pins causes the sensor to emit an analog voltage on the other pins. A resistive load between the output pins and ground sets the sensitivity of the detector. Please note: that the picture in the datasheet for the top configuration is wrong. Both configurations have the same pinout consistent with the bottom configuration.The resistive load should be calibrated for your particular application using the equations in the datasheet, but a good starting value for the resistor is 20 kO.

We offer a Pololu breakout board that makes it easier to interface with these sensors.
