The global humidity sensor market size was valued at USD 1.38 billion in 2024 and is projected to reach USD 2.54 billion by 2030, growing at a CAGR of 11.0% from 2025 to 2030. Humidity sensors are capable of measuring moisture levels in the air in real-time with high accuracy, making them essential for a variety of applications across multiple industries.

The rising adoption of humidity sensors in moisture-sensitive applications—including food & beverages, healthcare, textiles, and other sectors—is expected to be a key driver for market growth. Additionally, regulations implemented by governments in developed regions such as North America and Europe have mandated the use of these sensors in industries such as food processing, printing, and textiles to ensure quality and safety. For example, the Food Safety and Standards Authority of India (FSSAI) requires the deployment of humidity sensors in the food and beverage industry, as elevated moisture levels can lead to contamination and compromised product quality. Moreover, the growing demand for contactless sensors, which can be deployed in potentially hazardous environments such as areas exposed to radiation, is further propelling market growth.

In the healthcare sector, continuous improvements in infrastructure have emphasized the importance of advanced sensor technologies to maintain optimal environmental conditions for patient care, equipment storage, and overall facility management. Maintaining proper humidity levels, generally between 30-60%, enhances patient comfort and reduces the risk of respiratory issues, infections, and other health complications. Additionally, humidity sensors are critical for minimizing microbial growth in operating rooms and ensuring sterile conditions during surgeries, which has further contributed to the expansion of the global humidity sensor market.
