NDIR CO2 Sensor Module MH-Z14B
Summary:
MH-Z14B is a dual channel NDIR CO2 sensor. The appearance structure of this sensor is often one of the reasons for its selection. The MH-Z14B CO2 sensor starts at 0ppm, so it is very suitable for the agricultural field.
Feature:
* Warm up time 10s
* Min range 0ppm
* Max range 50000ppm
APPLICATION
The World Health Organization's "Indoor Air Pollution and Health" pointed out that the current level of indoor air pollution is 5-10 times higher than outdoor pollution, and 4% of global diseases are related to indoor air quality, and about 2 million people die prematurely each year from diseases caused by indoor air pollution.
Winsen is a world-renowned gas sensor manufacturer and supplier. A variety of sensors are intelligently combined and developed to form the overall concept of the module. The extremely flexible assembly combination can meet the sensitivity, corresponding speed, stability, power consumption and size requirements of all air purifiers on the market.
