Gas Sensor (MQ9) Carbon Monoxide

The Gas Sensor module is useful for gas leakage detection (in home and industry). The MQ9 sensor can detect Carbon Monoxide, Coal Gas, and Liquefied Gas with adjustable sensitivity via the board's potentiometer.

The detector on the base can be switched with different sensors to detect specific target gases.

• Detects Carbon Monoxide at 10-1000ppm and Gas at 100-10000ppm
• Stable performance, long life, low cost
• Fast response
• Wide detection range
• Simple drive circuit
