NDIR CO2 Sensor MH-Z19B
Summary:
MH-Z19B 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 compensation; and it has UART output and PWM output. It is developed by the tight integration of mature infrared absorbing gas detection technology, precision optical circuit design and superior circuit design.
Feature:
* High sensitivity, low power consumption
* Good stability
* Multiple output modes: UART, PWM
* Long lifespan

APPLICATION
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.
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.
