In order to monitor relative humidity, a capacitive humidity sensor sandwiched a thin metal oxide strip between two electrodes. The relative humidity of the atmosphere affects the metal oxide’s electrical conductivity.
The three main application areas are commercial, industrial, and weather.
The relative humidity (RH) of the air is sensed, measured, and reported by a humidity sensor, which also establishes how much water vapor is present in a gas mixture (air) or a pure gas.
The global capacitive humidity sensor market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
A semiconductor digital temperature and capacitive humidity sensor with good durability and little characteristic fluctuation (5%RH or less*) even in high temperature and high humidity situations will be available under the trade name MW3827 from MinebeaMitsumi Inc.
This product’s specially created semiconductor device structure allows it to maintain high reliability while suppressing aging degeneration.
Home appliances like air conditioners, air purifiers, and refrigerators as well as environmental monitoring devices like temperature and humidity meters and heat stroke meters all use temperature and humidity sensors.
Demand has increased recently as a result of the growth of IoT technologies and smart city efforts.
This product, which we are releasing for the first time, achieves accurate sensing over the entire range from low to high humidity (0 to 100% RH), and suppresses output error and accuracy deterioration that could occur due to water droplets and dust contamination (the existing product is susceptible to those).
Sensing of capacitive humidity from E and E. Outstanding linearity, high sensitivity, long-term stability, and remarkable reproducibility of the sensor characteristic are all features of the capacitive humidity sensors HCT01, HC109, HMC03M, HC103M2, and HC102.Capacitive humidity sensor with pre-adjustment.
The HCT01 humidity and temperature sensor combines the best workability and most cost-effective integration of the humidity sensor into application with high-quality, long-term verified thin-film sensor technology.
The humidity sensor is already set from the manufacturer, eliminating the need for a laborious humidity adjustment. To accurately determine a dew point, the temperature is measured using a highly accurate thin-film element.
The humidity sensor’s DFN enclosure provides the maximum amount of mechanical protection for the sensor and makes it easier to process using the common reflow soldering method. The surface of the active humidity sensor has a protective coating placed to it to protect it from contaminants including dust, salt, and chemical pollution.
