NDIR CO2 Sensor MH-410D

Summary:

MH-410D infrared gas sensor is a miniature universal intelligent sensor, which adopts NDIR theory to detect concentration of CO₂ 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.

Feature:

* High sensitivity, low power consumption

* Temperature compensation, excellent linear output

* Excellent stability

* Long lifespan

CO2 Detector

Most people spend about 90% of their time indoors. The air we breathe indoors and our health are affected by many factors, including outdoor air quality, the movements of people indoors, and the design, construction, operation and maintenance of buildings.

Indoor Air Quality Monitoring

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.

Smart Agriculture Greenhouse

Compared with traditional agriculture, greenhouse planting is an intensive industry. In the current greenhouse projects, the main economic crops are vegetables, flowers, medicinal materials, etc. For agricultural planting, greenhouses can provide a relatively stable and controllable planting environment to improve the stable yield and quality assurance of crops. At the same time, greenhouse planting can also achieve mechanized control and reduce labor costs.

Smart Breeding

Livestock and poultry farming is the major emission of ammonia gas, and these ammonia gas react with the oxidation products of sulfur dioxide and nitrogen oxides to generate ammonium nitrate and ammonium sulfate, which are an important source of PM2.5.

Pollution Source Detection

The septic tank is a device for processing feces and filtering. The principle is that the solidified material is decomposed at the bottom of the pool, and the hydrated objects in the upper layer enter the pipeline and flow away, preventing the pipeline from clogging and providing solidified objects (feces and other garbage)with enough time to hydrolyze.
