Abstract
[来源：http://www.think58.com]
This design content is the coal gas leak detection meter design. Mainly includes was mad the sensitive part the choice, the hardware electric circuit design, the monolithic integrated circuit choice, A/D transforms, the monolithic integrated circuit software procedure design, the connection electric circuit and reports to the police the exchaust gas system and so on several aspects contents, and is stable and the intellectualization to the system carries on the attempt.
[资料来源：www.THINK58.com]
Uses the AT89C51 monolithic integrated circuit, selects gas sensor TGS202 to take the sensitive unit, uses the multi- sensors information fusion technology, the development may use in the family daily life and the small business unit's coal gas revelation examination.
