Why choose us?

Hardware advantage

High sensitivity sensor

The air quality monitor adopts high-sensitivity sensors and control chips, with high resolution and good stability during the measurement process.


It can detect temperature, humidity, PM2.5, PM10, TSP, atmospheric pressure, light, noise, odor, TVOC, CO2, formaldehyde, O3, CO, CH4, O2, SO2, NO2, H2, H2S, NH3 in the environment Wait. Comprehensively reflect all air quality indicators. It supports free collocation of measurement elements, and can measure up to 15 air indicators at the same time.

Large screen display

4.3-inch large-screen LCD display, the value is clear. Complete functions, you can directly touch the screen to operate, different pages have different functions.

Easy to install

It supports wall-mounted and ceiling-mounted installations, and there is a gourd hole on the back of the air quality detector for easy hanging.

Software advantage

Various signal outputs

The air quality monitor can transmit data through RS485, ETH, WIFI, 4G. Choose the WIFI transmission method to avoid the problem of wiring. Users can view the detection data through a computer or mobile phone at any time, regardless of distance.

Free cloud platform

Our company provides a free cloud platform to facilitate customers to view and manage data.

Limit value setting

In order to meet different usage places, our air quality detector supports setting the upper and lower limits of gas parameters.

Real-time alarm

When a high concentration of one or more gases is detected, the corresponding gas part on the screen turns red and an alarm is issued. In addition to page alarms, there are also email alarms, text messages, and phone alarms.

Historical data export

After the data detected by the air quality monitor is uploaded to the cloud platform, the platform will automatically save the data. When we need it, we can query the historical records according to the time period and generate tables, polylines, etc., and export and print the data. Daily and monthly reports can also be generated so that we can better grasp recent data changes and provide a scientific basis for formulating protective measures.

Air quality monitor features

The air quality detector is a product that can detect formaldehyde, PM2.5, TVOC, illuminance, noise, temperature and humidity and other gases in real-time. Small size, easy to move. Through its internal sensor, it can accurately measure the concentration of various pollutants. Alarm when the concentration exceeds the standard.

Air quality monitor working principle: The signal measured by the sensor is amplified by the operational amplifier, and the noise interference is removed by the filter circuit. Then through AD acquisition and 32-bit high-precision CPU processing and calculation, it is converted into a pollutant concentration value and displayed on the LCD screen.
