Product Review

PM2.5 fine particulate matters( 2.5 micrometers in diameter or smaller) which come from power plants/ industrial processes/ vehicle tailpipes/ wood stoves and even wildfires,
it impacts your health and can cause respiratory issues such as allergies/asthma/ COPD/ lung cancer etc.

Ecowitt PM2.5 Air Quality Monitor helps you monitor the concentration of PM2.5 fine particulate matter, it also has 6 grades air quality levels indicator(based on current AQI):
Good, Moderate, Poor, Unhealthy, Severe and Hazardous, to help you know the air quality and take corresponding measures to reduce the loss.

Features:
1)Indoor tempe and humidity
2)PM 2.5/AQI current and max value for 1h/24h/since last reset.
4)Temperature units C/F selectable
5)Battery power condition display
6)Rechargeable batteries and solar panel as backup power included

Update Rate: 10 minutess
Measure rang
1) Indoor temperature measure range: 14 to 140 °F(-9.9 to 60°C).
2) Indoor humidity measure range: 1% ~ 99%.
3) PM 2.5 measure range: 0~999ug/m3
Accuracy:>100ug/m3,±15%;<100ug/m3, ±15ug/m3 Resolution: 1ug/m3

Note:
1.1.The sensor is sensitive to liquid droplets - rain/fog/sprinkling. When the Dew Point is close to the outdoor temperature(T - D < = 2C), the PM2.5 reading will be very high(which is not the real condition). If mind, please don't buy.
2.The PM2.5 sensor needs to be recharged every two week(with solar power as back up) or five days(withought solar power as back up).
3.The sensor detects every 10 minutes to save the power consumption. Therefore it might not react quickly to the environment changing. If mind, please don't buy. Any problem, please contact us first.
