Infrared Gas Sensor

 

1. Introduction

 

MH-440V/D infrared gas sensor is a miniature universal intelligent sensor, which adopts NDIR theory to detect concentration of CH4 in air and has good selectivity, stable performance, long life, also is independent of Oxygen. The inside temperature sensor could be used for temperature compensation. This miniature infrared gas sensor is developed by the tight integration of mature infrared absorbing gas detection technology, micro machine workout and superior circuit design.

It is convenient in use and also instead of catalytic component, widely used in various occasions with flammable and explosion hazard gas.

3. Model selection

This product has two types for your selection:

MH-440V

3 pins—It is same as pins of catalytic sensor, and the linear output supplied is familiar with the ones of catalytic.

MH-440D

5 pins—The 3 pins of them are same as pins of catalytic sensor, and the other two pins are UART pins, which can communicate with circuit directly and offer more choices for users.
