Overview
- The MQ-5 gas sensor is sensitive to LPG, natural gas and coal gas.
- It could be used in gas leakage detecting equipment in family and industry.
- The resistance of the sensitive component changes as the concentration of the target gas changes.
- Sensitive for LPG, natural gas, coal gas
- Fast response and recovery
- Adjustable sensitivity
Features
- Continuous Analog output
- 3-pin interlock connector
- Low cost and compact size
