Humidity and moisture sensors are devices used to measure the content of water vapor in the air or in materials. They are widely used in industrial process control, environmental monitoring, agriculture, weather stations, and smart home systems to ensure that environmental conditions meet specific requirements. Humidity sensors can be based on different technologies, such as capacitive, resistive, or optical principles to measure relative humidity or absolute humidity. Moisture sensors typically measure the moisture content in materials, which is crucial for ensuring product quality and process efficiency.
