我们都知道空气是由氮气、氧气、和少量二氧化碳组成。但空气中的另外一种成分对于人的日常生活也是必不可少的,这就是水分。大气中有过多或过少的水分都会导致人们不舒服,甚至引起一系列健康问题。如对生活有重要影响的静电积累问题,就与空气中湿度过低有关。空气湿度也对常用的工程和建筑材料性能有很大影响。本文介绍一种采用新型相对湿度(RH)传感器的湿度计,能准确地 We all know that the air is composed of nitrogen, oxygen, and a small amount of carbon dioxide. But another component of the air is also essential for people’s daily life, which is water. Too much or too little air in the atmosphere can cause discomfort and even cause a series of health problems. Such as the life of an important impact on the accumulation of static electricity, with the air humidity is too low. Air humidity also has a significant impact on the performance of commonly used engineering and building materials. This article describes a hygrometer that uses a new type of relative humidity (RH) sensor that is accurate
