Emerging Advances Challenges and Future Directions for Temperature Sensors in Wireless Sensor Networks

The swift progress of Wireless Sensor Networks (WSNs) and Internet of Things (IoT) technologies has elevated the significance of temperature monitoring in industrial, environmental, and intelligent systems. However, core issues like measurement accuracy, energy efficiency, and system scalability continue to limit its widespread application. This paper explores recent advances in temperature sensing technologies in WSNs, addressing challenges such as accuracy, energy efficiency, and adaptability, while investigating related optimization methods. Through a review of relevant literature and evaluation of case studies, it examines the advantages and limitations of current technologies, thus highlighting major challenges and possible solutions. The results demonstrate that despite significant progress, challenges persist in adapting to dynamic environments and maintaining long-term stability, with future improvements expected to arise from the incorporation of innovative materials and advanced algorithms.
