The global humidity sensors market size is expected to reach USD 7.69 billion in 2024 and USD 14.93 billion by 2029, growing at a CAGR of 14.2% over the calculated period.
Humidity plays an essential role in determining the daily climate and the amount of water vapor in the gaseous state present in the air. Too little or too much humidity can be dangerous; for example, high temperature combined with high humidity can lead to health risks, especially for the very old and infants. Humidity detection and control are required in various industrial and household applications. Humidity sensors are very important devices that help measure ambient humidity. It is also used to measure humidity in the atmosphere, and such a device is called a hygrometer. Humidity sensors or hygrometers are used to detect, measure, and record the humidity and temperature of the air present in the atmosphere. The humidity sensor consists of two metal plates, and a non-conductive polymer film is placed between them. The non-conductive polymer film collects moisture from the air, which changes the tension present between the two plates. These voltage changes are converted into the appropriate digital readings. The most common units to measure humidity are dew or freezing point (DF / PT), parts per million (PPM), and relative humidity. Humidity sensors are used in a wide range of applications, including HVAC systems, weather stations, medical, textile, food, and automotive industries.
Fiber optic moisture sensors have several advantages over electronic sensors. Fiber Optic Humidity Sensors (OFHS) offer more benefits than electronic humidity sensors because of their properties, such as durability, portability, support in flammable environments, and higher temperature and pressure ranges.
Depending on the end use, the automotive segment is expected to dominate the market due to the increasing adoption of humidity sensors to ensure optimal regulation of the air inside the car. These sensors can help, in particular, prevent the windscreen from misting inside the passenger compartment. They are also used to monitor the dew point and air intake of cars. In the automotive industry, millions of people use capacitive humidity sensors in modern control circuits designed to combine fuel mixtures, control air conditioning systems, or detect foggy windshields.
Automotive companies around the world are focusing on the electrification of vehicles, where humidity sensors are widely used. According to EV-volumes.com, global plug-in vehicle deliveries in 2019 reached 2,264,400 units, 9% more than in 2018, clearly deviating from the growth rates of the previous six years, which were between 46 and 69%.
For example, the E + E Elektronik Ges.mbH humidity sensor HCT01 combines high quality, long-term proven thin film sensor technology with the easiest maneuverability and cost-effective sensor humidity integration in the application. Trending is the humidity sensor for the automotive market, based on the requirements of the AEC-Q100 quality standard, which sets the industry standards for the reliability, stability, and robustness of electronic components in the automotive industry.
Factors such as the growing demand for small-sized humidity sensors, the dizzying installation of personal weather stations, and developments in the automotive industry are driving the growth of the global humidity sensor market. However, the need to enhance the technical specifications of humidity sensors is supposed to impede the expansion of this market to some extent. Furthermore, the development and adoption of vertical farming and precision farming are expected to provide lucrative opportunities for the growth of the humidity sensor market globally.
