Description
The MQ-7 sensor is a carbon monoxide (CO) gas detection sensor used to detect harmful CO gas in air. It works using a tin dioxide (SnO₂) semiconductor sensing material whose electrical resistance changes when exposed to CO gas.
It is commonly used in gas leakage detection systems, air quality monitoring, and IoT safety projects.

- Operating voltage: 5V DC
- Heater current: ~150 mA
- Warm-up time: 24–48 hours (first use recommended)
- Output types:
- Analog output (AO)
- Digital output (DO via comparator)
