Application of air quality sensor in indoor environment monitoring system
The air sustains the survival of humans and creatures. The human body needs to inhale 10-12 cubic meters of air every day. The atmosphere has a certain degree of self-purification. The pollutants that enter the atmosphere due to natural processes are removed from the atmosphere through the self-purification process, thereby maintaining a clean atmosphere.

However, with the continuous development of industry and transportation, a large amount of harmful substances are discharged into the air, which changes the normal composition of air and deteriorates air quality. When we live in polluted air, our health will be affected.

With the rapid development of my country's economy, air quality testing has become more and more important. This is mainly due to the continuous improvement of people's living conditions, various indoor materials and decorations have caused serious pollution to the air environment. In addition, the widespread use of air conditioners has shortened people's ventilation time such as opening windows, causing pollutants to accumulate in a limited space, and the degree of pollution has become more and more serious, posing a great threat to people's health. Indoor air pollution mainly includes organic volatiles such as formaldehyde, benzene and TVOC.

Relevant experts pointed out that indoor environmental pollution can cause children's immunity to decline, physical development delays, induce blood diseases in children, increase the incidence of asthma, and greatly reduce children's intelligence. According to the survey results of the 'China Association for Standardization and China Children's Health Insurance Center for Disease Control and Prevention

In order to ensure the safety of indoor air environment quality, we can use an indoor environment monitoring system to monitor the indoor environment. The indoor environment monitoring system includes a multifunctional air quality sensor and an environmental monitoring cloud platform. The multifunctional air quality transmitter monitors various monitoring indicators and uploads them to the environmental monitoring cloud platform. The cloud platform collects, sorts and records the uploaded data .

Features of the indoor environment monitoring system solution:

1. Remotely monitor 11 indicators of indoor oxygen, carbon dioxide, carbon monoxide, PM2.5, etc.; 2. Free real-time monitoring on the cloud platform, supporting historical data query Export; 3. Provide mobile APP for free, and view indoor air quality data report through mobile phone in real time;

4. RS485 network communication, centralized upload of network signals; 5. Value over-limit alarm, support SMS alarm, telephone voice alarm, Mailbox alarm;

Multifunctional air quality transmitter

Multifunctional air quality transmitter RS-MG111-NO1-1-* is an air environment comprehensive index monitor, used to detect air environment PM2.5, PM10, temperature, humidity, pressure, light, TVOC, oxygen, carbon dioxide (CO2), carbon monoxide (CO), formaldehyde (CH2O) and other parameters are powerful and basically cover various indicators reflecting air quality.


1. Built-in measuring unit imported from Switzerland, which integrates a variety of measurement elements to detect it; 2. Using imported high-sensitivity gas detection probes, TVOC gas detection; 3. Using electrochemical and catalytic combustion sensors to detect the real-time concentration of each gas in the environment; 4. Unique dual-frequency data acquisition and automatic calibration technology; 5. Using high-performance signal acquisition circuit with high accuracy 6. Dedicated 485 route, stable communication;

Environmental monitoring cloud platform:

Environmental monitoring cloud platform is a web login platform specially developed to provide users with the most convenient service. The cloud platform is deployed on the public network server and can be easily connected to a variety of products. Customers do not need to have public network IP or domain name resolution services, nor do they need to set up their own servers, which saves server maintenance costs. At the same time, there is a 'Cloud Control' APP on the web and mobile phones, and the data can be viewed on the computer or on the mobile phone. Customers can log in with their account anytime and anywhere to conveniently check their own device status, query data records, download and print data, etc., and can also choose SMS alarms, email alarms and other services as needed. The platform is stable and reliable, and the number of connected devices exceeds 10,000. .

Indoor air quality is not only related to the quality of human life, but also deeply affects other creatures on the planet. We should consciously fulfill our environmental protection obligations, strive to improve human living standards, continuously improve air quality, and improve our living environment.

We are a performance driven culture that uses sensor solution to ensure continuous improvement.
