As people age, their bodies are less able to compensate for the effects of environmental hazards. Air pollution can aggravate heart disease and stroke, lung diseases such as chronic obstructive pulmonary disease and asthma, and diabetes. This leads to increased medication use, more visits to health care providers, admissions to emergency rooms and hospitals, and even death.

YGHA8 pm2.5 indoor air quality monitor uses Led digital display with 180 degree angle, the pm2.5 digits occupy most area of the screen so you can see it clearly in a far distance. Built-in lithium battery let you measure PM2.5 value at anytime and anywhere. After charging full, it could be used for 8 hours. This indoor air quality monitor working environment is -9~50 degree, and the humidity range is 20%~90%RH, so you can use it at ease. This pm2.5 indoor air quality monitor measure the pm2.5 in the air by laser scattering, there is a built-in sensor in it. And the pm2.5 measuring range is 0~999ug cubic meter. When the value display on the screen is below 50, it shows the air quality is good. 51~100 shows the quality is moderate. Under these two conditions, the value display in green. But if the value is in 101~150, it shows the air quality is unhealthy for sensitive groups. When the value is in 151~200, it shows the air quality is unhealthy for all groups. In 201~300, it shows the air quality is very unhealthy. When the value is above 300, it shows the air quality is hazardous, we have to do something to improve the air quality at that time. While the value is above 100, the value will display in red and flashing. And the measure resolution is 10ug per cubic meter. This PM2.5 is also a hygrometer and thermometer, built-in temperature and humidity sensor can detect temperature and humidity in real time. The pm2.5 air quality monitor is also a clock.

With this background it is easy to see how important it is to understand the air quality in a home and, as appropriate, integrate indoor air quality monitor into a smart home so systems can be triggered to address air quality issues. If the place you lived is in poor quality, take this pm2.5 air quality home to take care of breathing health.
