The Global Humidity Sensor Market size is expected to reach $1.6 billion by 2025, rising at a market growth of 8.2% CAGR during the forecast period.
A humidity sensor or hygrometer can sense, measure, and record the air temperature and moisture present in the atmosphere. Humidity sensors are built of two metal plates and a non-conductive polymer film which is placed between the plates. The non-conductive polymer film absorbs air moisture and changes the current voltage between the two plates. Such voltage adjustments are converted into accurate digital readings. Humidity sensors are categorized into relative humidity sensors and absolute humidity (A.H) sensors. The most common types of units used to measure humidity are parts per million (PPM), dew or frost point (DF/PT), and relative humidity. These sensors are used in a range of applications such as HVAC systems, textiles, food processing, medical, weather stations, and automotive industries.
Humidity sensors can, with high accuracy, sense the levels of moisture in the air in real time. The utilization of these sensors is escalating in moisture-sensitive industries like food & beverages, healthcare, and textiles. This is a critical factor which can contribute towards the exponential growth of the market. Apart from this, government regulations in developed economies like North America and Europe have mandated the deployment of these sensors in industries like printing, food processing, and textile. For instance, the Food Safety and Standards Authority of India (FSSAI) have made the adoption of these sensors mandatory in the food & beverage industry. The reason being, higher levels of moisture can lead to contamination and harm the food quality. Another prominent factor that can stimulate market growth is the high demand for contactless sensors. This demand is associated with the potentially hazardous environments like places exposed to radiations.
