微雪电子 MQ-7 一氧化碳气体传感器用户手册说明书 1 MQ-7 Gas Sensor 用户手册 1. 产品特性 原理：MQ-7气体传感器所使用的气敏材料是在清洁空气中电导率较低的二氧化锡(SnO2)。当传感器所处环境中存在一氧化碳气体时，传感器的电导率随空气中一氧化碳气体浓度的增加而增大。2. 主要用途 家庭用气体泄漏报警...
1. Features MQ-7 gas sensor applies SnO2 which has a lower conductivity in the clear air as a gas-sensing material. In an atmosphere where there may be carbon monoxide in a certain density, the conductivity of the gas sensor raises along with the concentration of carbon monoxide increases.2...
