How do we measure humidity
WebSep 22, 2024 · Resistive humidity sensors place a pair of electrodes on a salt or conductive polymer and measure the resistance between them. This is less sensitive than capacitance, quite nonlinear, and highly temperature dependent. Humidity measurement would need fairly complex circuitry, including temperature measurement. WebJun 6, 2024 · What is Relative Humidity and Why do we need to measure? For human life, humidity affects health a lot. If the humidity is too high 90%, people will increase the risk of arthritis, cough, asthma, headaches and several other chronic diseases. Irritating fatigue, too high humidity is also a condition for harmful bacteria and fungi to grow.
