Product Description

This product is a multifunctional air quality monitor with wifi Tuya moduel that detects Carbon dioxide ( CO2 ),Formaldehyde (HCHO), Total Volatile Organic Compounds (TVOC), Particulate Matter <2.5 micron-sized particles (PM2.5/1.0/10), Temperature, and Humidity with clock and record function. As a scientific air quality detection device, it combines multiple air sensors with a built-in fan to allow real-time monitoring of Carbon dioxide ( CO2 ),formaldehyde (HCHO), total volatile organic compounds (TVOC), PM2.5/1.0/10, temperature, and humidity on its digital LCD display, people can check the air quality levels on the mobile phones after connect Tuya app .

It is connected to mobile Phones by wifi . we have build Tuya moduel into PCBA .

So when people use it , only if he download Tuya APP .and connect it to mobiles
by wifi ,then he read the air quality levels on the mobiles ,it is so smart and Convenient.
the whole process will need mins .

1 Q: What the test index are include for air quality monitor? A : CO2 : is PM2.5: is main for smog(PM1.0 and PM10 are the same); HCHO: is for formaldehyde; TVOC: is main for benzene,etc Volatile organic compounds; AQI: is for Integrated air quality index.

2. Q: What is the safe range for formaldehyde (HCHO) and TVOC? A : HCHO≤ 0.10mg / m3 TVOC≤ 0.60mg / m3 According to (“indoor air quality standards” GB / T 18883-2002 and GB 50325-2001 Class II civil construction).

3 Q: What is the standard range for PM2.5? A: Good 0~12 Medium 12~35 safe value 35~70 Unhealthy more than 70

4 Q: Why does the products make a sound when working? A : As PM2.5 detection need to collect a lot of mobile air, the inner fan needs strong operation to ensure accurate detection.

5 Q: How much range of detection of formaldehyde concentration detector,how many square meters? A : Test area≤ 50m3, room should be set 1~3 testing points; 50m3 ≤ Test area≤ 100m3, room should be set 3~5 testing points; ≥100m3, the points should more than 5 points. Testing points is on a diagonal or plum blossom evenly distributed, would more better. The height of the sampling point: in principle,consistent with the human breathing. Relative height of 0.5m ~ 1.5m between.

6 Q: which kinds of air index exceeded, would lead to Alarm sound? A: Just HCHO data more than 0.10mg / m3, would lead to Beep sound.
