Sensor in the Air Quality Monitoring Industry

As one of Winsen's core business areas, we pursue accuracy and longevity with excellent self-calibration capabilities. Indoors, we help users save energy through demand-controlled ventilation. Outdoors, we combine the most cutting-edge UAV for atmospheric environment detection and management.

Take Action on Air Pollution

Air pollution is the most pressing environmental health problem facing humanity. The presence of smog, dust, and toxic and harmful gases not only affects the respiratory system, but may also induce a variety of diseases. Long-term exposure to particulate matter (PM2.5), nitrogen dioxide (NO2), ozone (O3) and nitrogen oxides (NOx) with a diameter of ≤2.5µm is associated with a higher risk of respiratory disease and obesity, blood sugar disorders and risk of type 2 diabetes. For every 10 μg/m³ increase in PM2.5, the risk of cardiac arrest increases by 1% to 4%. The improvement of living standards has made people pay more and more attention to the impact of air pollution on physical health. Various air detection instruments and ventilation systems are playing an active role, and the core of these devices is the sensor. Sensors can't bring you fresh air, but they are your stewards and necessities for getting fresh air. We make sensors for people around the world that measure carbon dioxide and air quality to make better decisions for yourself and the environment

The Same Measured CO, the Different Measurement Methods

CO detection in underground parking 
Temperature and humidity, CO2 detection in subway
CO2 detection in shopping malls, supermarkets, hotels and other public places
Indoor PM2.5, formaldehyde, CO2 detection
Outdoor air pollution detection
Outdoor dust detection 

Saving Energy in Air Conditioning Systems with Winsen CO2 Sensors

The energy consumption of processing fresh air accounts for more than 20% of the energy consumption of air conditioners. In order to save operating costs, some shopping mall operators turn off the fresh air volume to a very small amount, or even close it completely, resulting in poor air circulation and fresh air cannot be replaced indoors. Harmful gas cannot be discharged, it is easy cause indoor air pollution.

Winsen's solution is to adjust air flow as needed by measuring carbon dioxide levels. Reduce energy costs by up to 50% while improving health and preventing the spread of viruses. In commercial buildings, the number of people visiting can vary widely. You can save a lot of energy by changing the airflow of heating or cooling as needed. The main source of indoor CO2 in office buildings is people's breath, and good indoor CO2 concentrations are usually around 400ppm. For rooms with different occupants, individual fans and valves can be controlled through carbon dioxide measurement, thereby creating a better indoor environment and saving energy.

Our Ultimate Pursuit of Dust Sensors

For measurement objects of different particle sizes, for example, the dust sensor for households mainly monitors smoke and dust, and the dust sensor for automobiles mainly monitors fine dust (PM2.5) and raise dust, sand storm (PM10), etc.
Different algorithms chosen by Winsen to achieve more precise selectivity:
1) The choice of wavelength and band is different
2) The circuit design of information processing is different

The application of ammonia sensors in different industries

Many people may not know much about ammonia, but they must have smelled it. There are ammonia existence in unclean toilets, crowded people etc. As a "useful" and "toxic" gas, ammonia gas exists in all walks of life, and sensors used to measure ammonia gas are also widely used in different industries.

The application of PM2.5 sensors in different industries

Fine particles are also called PM2.5. Fine particles refer to particles with a diameter of air dynamic equivalent in the ambient air less than or equal to 2.5 microns. It can be suspended in the air for a long time. The higher the concentration in the air, the more severe the air pollution is. The impact of PM2.5 on the atmospheric environment and human health is also greater, which is the main murderer who leads to black lungs and haze days.

The application of MEMS sensors in different industries

MEMS sensor is a cutting -edge research field developed on the basis of microelectronics technology. After more than forty years, it has become one of the major scientific and technological fields of the world. It involves a variety of disciplines and technologies such as electronics, machinery, materials, physics, chemistry, biology, medicine, etc., and has broad application prospects.

The application of infrared gas sensors in different industries

Compared with other types of gas sensors, infrared gas sensors have a lot of advantages, such as good selectivity, long life, no dependence of oxygen, small interference by the environment, not easy to poison, high accuracy, etc. With the development of sensing technology, more and more advanced infrared gas sensors have appeared on the market.
