HTC-2 Temperature & Humidity Meter with Digital Clock IXBH5N160G BIMOSFET Monolithic Bipolar MOS Transistor 1600 V Flexible Architecture with 4KB sectorsThe amount of water vapour in the air is measured with a hygrometer. When the humidity level reaches above 50%, a dehumidifier is required because humidified air condenses on cold surfaces (window frame wallpaper), creating an environment suitable for the growth of moulds and mites. When humidity falls below 40%, air affects the nasal mucous membranes and irritates the respiratory system, necessitating the use of a humidifier. Heating and air
