Waveshare MQ-7 Gas Sensor Overview
The Waveshare MQ-7 Gas Sensor is a dedicated carbon monoxide detection module based on the MQ-7 sensing element. It’s designed for real-time air quality monitoring, generating voltage-based and digital signals to trigger alarms or air treatment devices when CO levels rise.
Key Features of Waveshare MQ-7 Gas Sensor
- High sensitivity to carbon monoxide for accurate detection
- Output voltage increases in proportion to gas concentration
- Fast response and rapid recovery for timely alerts
- Onboard potentiometer allows adjustable sensitivity
- Digital signal output to interface directly with controllers
- LED indicator shows output status at a glance
- Fast shipping across India from Zbotic
Applications and Use Cases
- Residential CO alarms to protect families from gas leaks
- Industrial safety systems in factories and workshops
- Parking garage monitoring for exhaust buildup
- Integration into HVAC units for air quality control

Frequently Asked Questions
What gas does the MQ-7 sensor detect?
The Waveshare MQ-7 sensor is specifically tuned to detect carbon monoxide (CO) and provides proportional voltage and digital outputs based on CO concentration.
How do I adjust the sensitivity of the MQ-7 module?
Sensitivity is set via the onboard potentiometer. Turn it slowly while observing the digital output or LED indicator until it triggers at your desired CO threshold.
Can I interface this sensor with an Arduino or Raspberry Pi?
Yes. Use the digital output pin to connect to a GPIO/input pin on your microcontroller. Read the HIGH/LOW signal or measure the analog voltage (if supported) to integrate CO monitoring in your project.
