1pc ZCE04B 4-in-1 Industrial Gas Detection Module

[shortdesc]Application:It can be used in the environment of factory gas leakage, underground operation, tunnel detection, coal mine detection and so on. It can be worn by human body or hand-held into the detection place, or it can be used in fixed place to detect the current environmental gas concentration and remindpersonnel to be safe.Feature:High integration, small size,Good stability and fast response,Real-time serial port output concentration, easy to use[/shortdesc]Production Description:The 4-in-1 detection module ZCE04B is mainly aimed at various places where ambient gas detection is required. The product contains four gas sensors (expandable for CO, H2S, O2 and CH4 gases) and a signal processing circuit board. The module has good selectivity and stability. The module can output the current concentration values of the four gases in real time through the digital serial port output. It can be used in handheld devices or fixed devices to detect the current concentration of ambient gas. This module is a general-purpose miniaturized product that closely combines mature sensor detection technology and sophisticated circuit design.Feature: High integration, small size, Good stability and fast response Real-time serial port output concentration, easy to use Application:It can be used in the environment of factory gas leakage, underground operation, tunnel detection, coal mine detection and so on. It can be worn by human body or hand-held into the detection place, or it can be used in fixed place to detect the current environmental gas concentration and remindpersonnel to be safe.
