NDIR CO2 Sensor Module MH-Z14B
Summary:
MH-Z14B NDIR Infrared gas module is a common type, small size sensor, using non-dispersive infrared (NDIR) principle to detect the existence of CO2 in the air, with good selectivity, non-oxygen dependent and long life. Built-in temperature sensor can do temperature compensation; and it has digital output and analog voltage output. This infrared gas sensor is developed by the tight integration of mature infrared absorbing gas detection technology, Precision optical circuit design and superior circuit design.
Feature:
* Gold plating technology for cavity, waterproof and anti-corrosion
* High sensitivity, low power consumption
* Good stability, long lifespan
* Temperature compensation, excellent linear output
* Output modes: UART, PWM
* Anti-water vapor interference, no poisoning

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.
Winsen Technology has provided accurate gas detection solutions for more than 1,000 fresh air enterprises, which has also established the influence of Winsen sensors in the air purification market. In the future, Winsen will launch more intelligent and miniaturized all-in-one integrated modules to meet the various needs of different customers in the ventilation system market.
