Background:

Air quality is becoming an important environmental issue. Pollution can reduce the quality of the air we breathe, which can lead to health problems. For example, bad air can exacerbate allergies and respiratory problems such as asthma. In addition, certain everyday activities may release harmful gases, and in extreme cases, harmful gases like carbon monoxide can cause death. Therefore, gas sensors have attracted more and more manufacturers' interest. Gas sensing is not a new technology. Gas detection devices with integrated gas sensors are already used in defense and industrial security and form a highly regulated and mature market.

The future of gas sensors：

Faced with the challenges of air quality and increasing environmental awareness, people are creating new applications and opportunities. Including consumer gas sensors, such as home devices, wearables and smartphones, or gas sensors for buildings, cars, such as indoor/in-vehicle air quality monitoring. Gas sensing technology is a complex field with many different sensitive modalities. Overall, the choice of gas sensing technology depends on price, size, power consumption, sensitivity and response time.

Fixed CO2 gas sensor：

The explosion-proof carbon dioxide gas alarm of Jingxun is specially developed and produced for the harsh environment. The core detection device is the professional detection of carbon dioxide concentration sensor probe. It has the characteristics of wide measurement range, high precision, good linearity, good versatility, convenient use, convenient installation, long transmission distance and moderate price. Industrial-grade sensor for continuous monitoring of gas concentrations. The certificate is complete and there are many options. Available on demand. The alarm controller has a variety of options, and the optional external control ports are abundant. With high-definition LCD color screen display, industrial-grade high-definition interface, 320*240 resolution display is intuitive. It can be controlled remotely and can claim to switch the interface to view the data.

NOx monitoring system：

The NOx monitor uses a pumped sampling method that draws air directly from the atmosphere. The gas entering the instrument sequentially passes through the gas treatment loop such as the trap, and finally enters the nitrogen and oxygen analyzer. Through advanced detection technology, the concentration of nitrogen and oxygen in the gas can be measured. The NOx online monitoring system is suitable for gas detection and analysis under the conditions of low dust, high temperature and high humidity.

The main principle is: the sampling unit collects the flue gas or the measured gas on site, and the pretreatment unit cools, dehumidifies and filters the dust. Keep the temperature and humidity of the measured gas within a certain range, and the gas detection unit will detect and analyze the delivered gas. The measured gas concentration is displayed on the display in real time. And the data signal is transmitted to PLC or computer terminal, and can also be transmitted to the local environmental protection bureau or cloud server or network through wireless GPRS (DTU). Users can read data from the server, enabling global network monitoring and analysis. The entire process is automatic and requires no human intervention.
