About - AQI Sensor

RS-MG111-*-1 is an air quality detector for measuring formaldehyde, particulate matter, TVOC, temperature, humidity, CO2, O3, CO, CH4, O2, SO2, NO2, H2, H2S, NH3, air pressure, light, and it comes with an additional measurement of AQI. Its design allows users to easily move around the house and take measurements in different rooms.

AQI sensor


RS-MG111-*-1 AQI meter adopts electrochemical and catalytic combustion measurement principles. The equipment shell has multiple small holes to ensure air circulation and higher measurement accuracy. This indoor air quality index sensor has 18 elements to choose from, and one device can measure up to 11 elements at the same time. Powerful. According to different output methods, it is divided into two types: RS485 AQI sensor and Wifi AQI sensor. The measured value can be uploaded to the free cloud platform via a 485 signal or wifi signal.

FAQs - Air Quality Index Sensor

  • Understand indoor air pollution: indoor air quality monitor can measure indoor PM2.5, PM10, carbon dioxide, temperature and humidity, and other elements, reminding people to pay attention to whether the indoor environment is healthy and suitable for living.
  • Monitoring air quality pollutants: Indoor air quality monitors can monitor these toxic and harmful gases: formaldehyde, ammonia, carbon monoxide, sulfur dioxide, nitrogen dioxide, TVOC, and other pollutants.
  • Establish an air quality big data management platform: indoor air quality monitor, which used to be just a simple instrument, now it can establish a real indoor air quality management system through the Internet of Things. Air quality data does not need to be manually collected and is automatically collected and transmitted to the online environmental management cloud platform. Users can directly understand environmental data through mobile phones and PC.

The warranty period of the monitor is 2 years. The warranty only applies to manufacturing defects.

After the air quality index sensor is installed, it will automatically detect various elements of the current environment, and upload the detection results to the free cloud platform or -K platform through RS485 or wifi signals, and users can log in to view the data freely.

AQI sensors are widely used in building HVAC, building energy-saving, smart homes, schools, hospitals, airport stations, and other places.
