The MQ-7 carbon monoxide gas sensor is a sensor used for gas detection in cars, homes or industrial areas.

MQ-7 carbon monoxide gas sensor features:

• Working voltage: 5V DC
• Microprocessor compatible TTL output.
• Analog output. The output voltage varies proportionally to the gas concentration in the air.
• High sensitivity. It precisely measures the concentration of carbon monoxide (CO).
• Measuring December: 10-10000 ppm
• Long working life and stability
• Fast response time and good selectivity
• Ease of plug/unplug for testing with socket probes.
• Works compatible with Arduino and other development boards.
