Multi-parameters gas detection instrument design and realization method

摘要

A kind of based on PIC18F4520 MCU multi-parameter gas detection instrument design and realization method was introduced using electrochemical sensor, but at the same time detection methane, oxygen, carbon monoxide three kinds of gas in the air content, and have transfinite alarm, display, and other functions, and temperature detection can be widely used in coal mine working environment place, has certain application value.
