1、 Interior decoration of new residence
The new home looks bright and bright, but it also lurks many hazards. The continuous release of formaldehyde, benzene, TVOC and other harmful gases from furniture and building materials has caused great health damage at home for a long time. Especially for the elderly and children with low physical resistance, it is very easy to cause major health problems such as leukemia and cancer.
MIX2011 semiconductor air quality sensor has a service life of up to 10 years, low power consumption, high sensitivity and long-term stability. When the detected gas exists in the ambient air, the conductivity of the air quality sensor changes. The higher the concentration of the gas, the higher the conductivity of the air quality sensor. It is widely used in domestic gas alarm and air quality detector. It is the first choice for indoor air detection in new homes.

2、 Indoor gas pollution
Co, nitrogen oxides and high concentration oil fume produced during cooking three meals a day are "health killers", not to mention the strong carcinogens hidden in them. Even if the ordinary range hood is turned to the maximum gear, it can not be fully absorbed in the face of Chinese frying. If it diffuses into the air, it will bring potential health hazards. In addition, if someone smokes at home, it will also bring the harm of second-hand smoke to the family.
Maxon infrared carbon dioxide gas sensor has the characteristics of small volume, low power consumption and high precision. CO2 sensor has a variety of output interfaces such as UART and PWM, which can be calibrated separately. It is very convenient to connect products with users. It can be widely used in HVAC ventilation control, indoor air quality detection, etc.

3、 Outdoor pollutant carrying
When we go out for activities, our body will become a huge "host". Various pollens, PM2.5, dust particles, automobile exhaust and other pollutants adhere to the human body and follow into the room, further damaging the indoor environment and affecting our health.
Mixsen MIX6070 particle matter sensor is a laser digital particle detection sensor, which can be used to detect small particles in the air indoors and outdoors.
It has been tested strictly in various harsh environments, with reliable accuracy, and can detect or control environmental particulate pollution economically and accurately; It can work continuously for 30000 hours and operate accurately to ensure that the product can achieve the predetermined function.
