The global humidity sensor market size was valued at USD 1.38 billion in 2024 and is projected to grow at a CAGR of 11.0% from 2025 to 2030. Humidity sensors can sense the levels of moisture present in the air in real-time with high accuracy. The rising adoption of these sensors for moisture-sensitive applications in industries, such as food & beverages, healthcare, and textile, among others, is expected to drive the market growth. Regulations laid down by governments of developed economies in regions, such as North America and Europe, have mandated the use of these sensors in industries, such as food processing, printing, and textile. For example, the Food Safety and Standards Authority of India (FSSAI) mandates the usage of these sensors in the food & beverage industry as higher levels of moisture can cause contamination and affect the food quality. The increasing demand for contactless sensors that can be deployed in potentially hazardous environments, such as places exposed to radiation, is a major factor driving market growth.

Constant improvements in healthcare infrastructure have highlighted the need for advanced sensor technologies to ensure optimal environmental conditions for patient care, equipment storage, and overall facility management. For instance, maintaining appropriate humidity levels, generally between 30-60%, helps enhance patient comfort and can reduce the risk of respiratory issues, infections, and other health complications. Furthermore, the need to minimize microbial growth in operating rooms and maintain sterile conditions to lower the risk of infection during surgeries has contributed to the industry's expansion. The development of green buildings and the need to incorporate sustainability in urban environments has further encouraged the use of humidity sensors. These devices help optimize heating, ventilation, and air conditioning (HVAC) systems by adjusting operations based on real-time humidity levels, thus reducing energy consumption. In smart green buildings, humidity sensors can be integrated with IoT systems for real-time monitoring and data analysis, allowing for proactive maintenance and improved operational efficiency. The trend of indoor gardens or green roofs in modern infrastructure has further boosted the need for humidity sensors to ensure that plants receive the right amount of water in these settings while conserving resources.

The adoption of microelectromechanical systems (MEMS) technology in sensing applications has substantially increased in recent years, aiding the demand for humidity sensors based on this technology. Significant investments are being made to launch products that provide increased value to customers, such as wireless technology, low power consumption, miniaturization, and enhanced portability. New materials, such as graphene and nanostructures, are improving the sensitivity and response time of humidity sensors, allowing for quicker and more accurate readings. Moreover, some sensors are now equipped with energy-harvesting technology, using ambient energy sources such as light or heat to power themselves, making them more sustainable. Additionally, manufacturers are now developing sensor solutions that can measure multiple parameters, including temperature, humidity, and air quality, in a single device, thus providing more comprehensive environmental data. For instance, in August 2024, Renesas Electronics Corporation launched the RRH62000 all-in-one sensor module for indoor air quality monitoring. The solution integrates multiple sensor parameters in a compact manner to detect particulate matter (PM), total volatile organic compounds (TVOC), estimated carbon dioxide, temperature, and humidity.

Type Insights

The absolute humidity sensors segment accounted for the largest revenue share of 61.3% in the global market in 2024. The demand for these sensors is expected to grow substantially, driven by advancements in technology and the need for accurate environmental monitoring across various sectors. Innovations in sensor technology, such as miniaturization and improved accuracy, are enhancing the capabilities and appeal of absolute humidity sensors. The variety of features offered by these sensors has driven their utilization across several major applications. For instance, increasing awareness regarding climate change and environmental conditions drives the need for precise humidity measurements in weather stations and research institutions. Additionally, the growing focus on energy efficiency and indoor air quality in residential, commercial, and industrial HVAC systems has driven steady demand for these devices, as they help optimize performance by providing accurate moisture readings.

The relative humidity sensors segment is expected to advance at the fastest CAGR from 2025 to 2030. This type of sensor measures the amount of moisture present in air relative to the maximum moisture amount that it can hold at a given temperature and is useful in applications such as weather stations, HVAC systems, and industrial processes. In HVAC systems, these devices monitor the relative humidity levels and provide accurate feedback that allows for adjustments to be made to maintain desired humidity levels. Moreover, the need to prevent mold and mildew growth and maintain integrity of building structures as well as health of occupants necessitates the maintenance of appropriate humidity levels. They are also crucial in greenhouse management, helping to create and maintain optimal growing conditions for plants by constantly monitoring their health, preventing the occurrence of fungal diseases and mold growth. Modern sensors are being designed to allow growers to log humidity data, thus allowing them to analyze trends over time. This information can guide future planting and cultivation strategies.

End Use Insights

The automotive industry accounted for a dominant revenue share in the global market in 2024, as humidity sensors are widely adopted to ensure optimal regulation of air inside the vehicle. Additionally, these sensors are useful in preventing fogging on windscreens and can efficiently monitor the air intake and dew point of cars. These devices further help ensure that the air circulated within the vehicle is neither too dry nor too humid, improving occupant comfort. In combination with anti-corrosion coatings, they can help protect the vehicle's structural integrity by preventing corrosion and rust formation. Advanced humidity sensors detect moisture in obscure areas such as the undercarriage, engine compartment, and inside doors, providing timely alerts and preventing any potential malfunction or failure that could risk passenger safety. These benefits highlight the importance of humidity sensors in vehicles.

The environmental segment is anticipated to emerge as the fastest-growing end use segment from 2025 to 2030, aided by the increasing need for temperature and humidity monitoring in indoor environments.
