The gas sensor module mhd2002 is based on intelligent sensor developed by Huiwen technology. It can be used to identify and detect the components and contents of methane and carbon monoxide in the air at the same time. The sensor module has the characteristics of anti alcohol interference, and can not generate false alarm in the high concentration ethanol gas atmosphere of 6000ppm. Mhd2002 series module is a multi-channel gas sensor composed of different material systems. It uses specific conditioning circuit and accurate algorithm to convert the response conductivity change into the corresponding electrical signal of gas type and concentration.

It can identify and detect methane and carbon monoxide, anti 6000ppm alcohol interference at the same time, high sensitivity, high resolution, low power consumption, long service life, provide UART, analog voltage signal, PWM waveform and other output modes with high stability, excellent anti-interference ability, temperature compensation and Zhuoyue linear output.
