Why does atmospheric environment monitoring use a large number of sensor technologies?
Various effective technical methods, such as spectroscopy, chromatography, mass spectrometry, color and mass spectrometry, etc., are used in atmospheric environmental monitoring. However, one of the technologies has been widely used and promoted in recent years, and this is related equipment that uses sensor technology. Then why the sensor technology is so widely used by the environmental protection bureaus, manufacturing companies, etc., the characteristics of the sensor technology are analyzed below:
1. Small integration
Due to the simple structure of the sensor, it is possible to miniaturize the device. The finished sensor components are small in size and can be integrated into various environmental monitoring instruments. And because of its small size, sensors with multiple parameters can be integrated in one device, making the instrument and equipment more comprehensive. For example, most of the handheld detection devices are manufactured using sensor technology. These handheld devices have good performance in safety inspections and danger warning.
2. Low cost
The cost of equipment manufactured by sensor technology is lower than that of related equipment using other technologies. This provides cost possibilities for large-scale and large-quantity deployment. The government can use lower-cost atmospheric micro-stations to complete the atmospheric environment monitoring coverage of the entire area and eliminate the blind spots in the area. The large amount of data collected by the atmospheric micro-station can be used as a beneficial supplement to the atmospheric standard station. Manufacturing companies can also deploy their own atmospheric micro-stations to prove that their emissions are within the standard limits, thereby avoiding corporate risks.
3. Fast response
Devices integrated with sensors can usually respond quickly and output data quickly. The time resolution is usually higher and the reversibility is better. Therefore, it has good applications in some emergency monitoring and hazardous gas monitoring. It also provides guarantee for long-term real-time online monitoring of environmental quality in the region. Law enforcement agencies can use real-time data to discover unlawful discharges and discharges in the region, and carry out timely law enforcement.
Of course, as a sensor technology also has its shortcomings. For example, high-precision monitoring equipment lacks accuracy, reproducibility and comparability problems, and detection limits for low-concentration chemical substances. But these do not affect its use of its advantages in atmospheric environmental monitoring. For such problems, other technologies can be used to make up for the lack of sensor technology. A variety of methods are used to verify the authenticity and accuracy of the data, and provide useful monitoring data for controlling the atmosphere.
