This mesh is designed so that ...

20161221· Me Gas Sensor includes a smoke sensor of type MQ2 which has good repeatability, longterm stability, short response time, and durable working performance. It is often used as a gas leakage monitoring device in family and factory, and suitable for detecting Liquefied Natural Gas (LNG), butane, propane, methane, alcohol, hydrogen, smoke, etc. Its black ID means that it has an analog port and ...

20160223· Both MQ5 and MQ2 are basically gas sensors but their range of sensing different gas levels vary. For example, MQ5 can sense LPG in a broader range of 200 ppm to 10000 ppm, where as the range of MQ2 for LPG is short and is from 5000 ppm to 10000 ppm. Similarly MQ2 is sensitive to smoke where as MQ5 is not that sensitive to smoke. So we can not choose MQ5 gas sensor to …
