Principle and Application of Air Quality Transmitter

Whether it is home decoration or factory building decoration, 'Golden Nine Silver Ten' is undoubtedly a good time for decoration. At this time, it is in the middle and late autumn, cool and suitable, and the climate is dry. Not only is it suitable for workers, but for decoration, the temperature and humidity in autumn are moderate. When the building materials are placed and used, even without special protective measures, they will not be deformed, cracked, or damp, and can perform better; at the same time, they will gradually dry The environment can also accelerate the solidification of the coating.

But at the same time, the threat of decoration gas has also risen sharply. The piles of paint, building materials, adhesives and other decoration materials continue to emit formaldehyde, and some harmful gases such as benzene and TVOC are also volatilized. These gases It is the culprit of indoor environmental pollution, which can cause great damage to the human body. Among these gases, formaldehyde and TVOC are recognized as the most harmful.

Formaldehyde was identified as a suspicious carcinogen by the International Agency for Research on Cancer (IARC) as early as 1995. Then in the announcement of the 2004 publication, formaldehyde rose from Class 2 carcinogen to Class 1 carcinogen Substances; TVOC can cause imbalances in the body’s immune level, affect central nervous system function, and experience dizziness, headache, drowsiness, weakness, chest tightness and other conscious symptoms. It may also affect the digestive system, causing loss of appetite, nausea, etc., which can damage the liver in severe cases. And the hematopoietic system, allergic reactions and so on.

It can be seen that these two decoration gases will cause great harm to the human body. How should we respond? If it is a home decoration, because the unit area is small, you can choose ventilation and other methods to deal with it; while the factory building is different, the plant area is huge, and the equipment is large, which will cause poor air circulation and difficult to clean up harmful gases. At this time, the factory can choose to install an air quality transmitter to monitor the system.

The air quality transmitter can not only monitor methane and TVOC, but also monitor environmental factors such as PM2.5, PM10, temperature, humidity, air pressure, light, O2, carbon dioxide (CO2), carbon monoxide (CO), etc. The ability to support the multi-functional use of the factory. Here is a detailed introduction to the air quality transmitter:

1. Air quality transmitter:

The air quality transmitter is a self-developed air environment comprehensive index monitoring It can be used to monitor PM2.5, PM10, temperature, humidity, pressure, light, TVOC, O2, carbon dioxide (CO2), carbon monoxide (CO), formaldehyde (CH2O) and other parameters in the air environment. The function is very complete and basically covers It reflects the various indicators of air quality. And the transmitter adopts the original imported sensor and computing chip, which has the characteristics of high precision, high resolution and good stability.

2. The working principle of the air quality transmitter:

The air quality transmitter has a built-in measuring unit imported from Switzerland to detect the air temperature and humidity; adopt foreign countries The imported high-sensitivity gas detection probe detects TVOC gas; electrochemical and catalytic combustion sensors are used to detect the real-time concentration of each gas in the environment.

3. Air quality transmitter installation and data upload method

When testing and using indoors, you can choose to mount the multifunctional air quality sensor on the wall or on the roof. , Upload data to RS-RJ-K local monitoring software via RS485 cable, or connect to the environment monitoring host RS-XZJ-100-Y-GPRS/4G, and upload data to remote web monitoring software cloud via GPRS/4G communication Platform

4. Monitoring software cloud platform

Users can log in to the cloud platform www.0531yun.cn through a variety of methods such as computer web pages, mobile apps, and WeChat official accounts. View the real-time data uploaded by the environmental monitoring host on the front-end interface, you can also view historical data in time periods, and download historical data in Excel or PDF format.

The cloud platform system can be remotely managed. Whenever and wherever the user is, he only needs to log in to the cloud platform with his account and password, he can modify the upper and lower limits of each factor and add manager information; once it appears If the value exceeds the limit, the system will notify the administrators added to the cloud platform by phone or SMS as soon as possible.

The prevention and control of decoration pollution cannot be accomplished overnight, nor can a single measure achieve immediate results. To reduce decoration pollution, we must first rationally design, follow the principles of simplicity and practicality, and fundamentally reduce pollution sources; secondly, in terms of materials, we must strictly select environmentally friendly and safe materials; for existing indoor air pollution, strengthening ventilation is the most effective Method.
