SMART SENSOR AS8421 4-in-1 Gas Detector Oxygen/carbon monoxide/hydrogen sulfide/combustible gas

Introduction

Gas Detector is an instrumentation tool for gas leakage concentration detection, mainly referring to portable/handheld Gas Detectors. Gas sensors are used to detect the composition and content of gases. It is generally believed that the definition of a gas sensor is based on the detection target, that is, any sensor used to detect the composition and concentration of a gas is called a gas sensor, regardless of whether it is used by physical or chemical methods. For example, sensors that detect gas flow are not considered gas sensors, but thermal conductivity Gas Analyzers are important gas sensors, although they sometimes use a more or less consistent detection principle. 

While many standard Gas Detectors were originally built to detect only one gas, modern multi-purpose or multi-gas detection devices are capable of detecting multiple gases at the same time. Some Gas Detectors can be used as individual units to monitor places with small working space, or can be combined or connected together to form a monitoring and protection system.
