The importance of 1. the indoor environment

The quality of all indoor environments is closely related to health. 2/3 of one's life is spent here; modern people live and work in an indoor environment for the whole day.80%～90%The contact time with indoor air pollutants is much longer than that outside, so the quality of indoor environment directly affects people's health. Studies have shown that indoor is not a safe place, and sometimes indoor pollution is more serious. A person needs every day1kilos of food2kg of drinking water, but the required air is10kg, indoor air quality (IAQ) It is particularly important for people's health protection, comfort and work and study efficiency. Therefore, it is very necessary to create a clean, healthy and comfortable home environment.

Major Sources of Indoor Air Pollution in 2.

1, latex paint, not environmentally friendly latex paint, or environmental protection grade is not enough latex paint, will contain formaldehyde andVOC；

2, wooden furniture paint, such as beds, wardrobes, cabinets, shoe cabinets, TV cabinets, tea tables, dining tables and other wooden, need to be painted, more or less contain volatile irritating smell things, such as formaldehyde, etc.VOC。 

3, poor quality plastic and rubber products, suchPVCPipes, rubber hoses, etc., poor materials will contain irritating volatile gases. Kan

4, curtains, fabric, etc., the newly bought goods in the processing process will also contain some pungent smell. Kan

5, household waste generated by ammonia, hydrogen sulfide, smoke and other odor.

How to deal with indoor pollution in 3.

First of all, attention should be paid to indoor ventilation, and windows should be opened regularly every day to keep the indoor air fresh; attention should also be paid to indoor environmental purification, such as placing activated carbon or green plants, especially when the house is newly decorated or newly added furniture, it should be confirmed Whether the indoor air quality meets the healthy living standards; if conditions permit, it is recommended to install air purifiers, fresh air systems, etc. to purify indoor air.

Air quality sensors are the core of air purifiers and fresh air systems. The quality and price of air quality are particularly critical. Here, a Japanese imported indoor air quality sensor is launched.TGS2602The sensor is used for formaldehyde, ammonia,VOCsIt has good sensitivity, small size, long life, and low price. It is very suitable for fresh air systems and air purifiers.

TGS2602Basic parameters

Range: 1-30PPM detection object: formaldehyde, ammonia,VOCs

For    Electricity:Vh = 5V；VC=5V

work    Consumption:280mW

Life Expectancy:>5Year

TGS2602The advantage                                           

Small size, long life, low cost

Right.VOCsHigh sensitivity with odor

Good repeatability and long-term stability

The application circuit is simple and conformsRoHSCertification

TGS2602 sensors have high sensitivity to organic volatile gases, in lineROHSRequirements, can be used for home, office environment ammonia, hydrogen sulfide detection, but also for building materials products volatilized benzene, toluene, etc.VOCGas is detected.
