Description: Carbon monoxide, coke oven gas and liquefied petroleum gas sensor - MQ9 - Analogue.
The module is equipped witha sensor of carbon monoxide, coke oven gas and liquefied gases - MQ9. The sensoris compatible withArduino and Raspberry,it is equippedwith a Grove connector so you can directly plug it into a Grove-Pi+ or Grove BaseShield anduseits capabilities,without the need for soldering.The power supply is 5 volts and communicates viaan analogue interface. A Grove-Pi+ overlay orADCis required to connect it to the Raspberry.There is a potentiometer on the board to adjust the sensitivity.
