Humidity Sensor Based on LaFe₀.₈₅Mn₀.₁₅O₃ Perovskite Prepared by Sol Gel Method

Abstract:

Humidity sensors are crucial for monitoring and controlling environmental conditions in diverse sectors such as agriculture, food and beverage processing, pharmaceutical industries, electronics, healthcare and biomedical applications, building environments, automotive systems, meteorology, and research laboratories [1]. Excessively high or low humidity levels relative to the ideal range can pose detrimental effects on both the environment and human health. For example, in the food industry, uncontrolled humidity can cause product damage, promote microbial growth, accelerate chemical degradation, and reduce the quality of raw materials [2]. In healthcare and biomedical environments. When the relative humidity is too low, it may dry out the skin and respiratory passages, making people more prone to infections. On the other hand, when RH is too high,it can support the growth of microorganisms such as molds, bacteria, and viruses [3]. Therefore, humidity sensors for monitoring and controlling moisture levels are essential for ensuring human comfort and maintaining high product quality. In recent years, various efforts have been undertaken to enhance the performance of humidity sensors, particularly through the development of humidity-sensing materials capable of providing high sensitivity, high stability, a wide detection range, low hysteresis, and optimal dynamic response, including fast response and recovery times [4-5].
