产品概述
The Grove - Gas Sensor (MQ9) module is useful for gas leakage detecting (in home and industry). It can detect LPG, CO, and CH4. Based on its fast response time, measurements can be taken as soon as possible. Also, the sensitivity can be adjusted by the potentiometer.
核心特点/优势
- Wide detecting scope
- Stable and long life
- Fast response and High sensitivity
应用领域
- 家庭燃气泄漏检测
- 工业气体监测
选型指南/使用建议
There're two steps you need to do before getting the concentration of gas. First, connect the module with Grove Shield using AO. Put the sensor in a clear air and use the program below to calibrate R0. Then, put the sensor in the target gas environment and calculate the gas concentration based on the RS/R0 ratio. Note that the relation between the ratio and concentration is nonlinear, and the measurable range is between 200 ppm and 10000 ppm.
