Environmental pollution is a major concern, particularly in modern cities, due to its significant effects on human health and the global economy. These pollutants must be continuously monitored to prevent negative impacts on the environment. The scientific community has done in-depth studies on optimal environmental sensors from theory to practice in recent years. These sensors can detect the existence of hazardous gases and quantify the amounts in the surrounding environment. Since sensor applications are anticipated to be further expanded, examining the crucial types of sensors, their characteristics, difficulties, and significant applications is essential. In this paper, different sensing methods and sensing materials adopted for detecting environmental pollutants are reviewed, focusing on hazardous gases like nitrogen oxides (NO ), ammonia (NH), carbon monoxide (CO), and sulfur oxides (SO ). The working principle of sensing technology adopted for fabricating sensors, sensing materials used, and essential sensing parameters like sensitivity, operating temperature, and detection range are thoroughly analyzed.
环境污染是一个主要问题，特别是在现代城市中，因为它对人类健康和全球经济有重大影响。必须持续监测这些污染物，以防止对环境产生负面影响。近年来，科学界从理论到实践对最佳环境传感器进行了深入研究。这些传感器可以检测有害气体的存在并量化周围环境中的含量。由于预计传感器的应用将进一步扩大，因此研究关键类型的传感器、它们的特性、难点和重要应用至关重要。本文综述了用于检测环境污染物的不同传感方法和传感材料，重点关注氮氧化物（NO ）、氨（NH）、一氧化碳（CO）和硫氧化物（SO ）等有害气体。对制造传感器所采用的传感技术的工作原理、使用的传感材料以及诸如灵敏度、工作温度和检测范围等基本传感参数进行了全面分析。
